Written by  Scribendi

Has this ever happened to you? While looking for websites for research, you come across a research paper site that claims to connect academics to a peer-reviewed article database for free.

Intrigued, you search for keywords related to your topic, only to discover that you must pay a hefty subscription fee to access the service. After the umpteenth time being duped, you begin to wonder if there's even such a thing as free journal articles.

Subscription fees and paywalls are often the bane of students and academics, especially those at small institutions who don't provide access to many free article directories and repositories.

Whether you're working on an undergraduate paper, a PhD dissertation, or a medical research study, we want to help you find tools to locate and access the information you need to produce well-researched, compelling, and innovative work.

Below, we discuss why peer-reviewed articles are superior and list out the best free article databases to use in 2024.

Why peer-reviewed scholarly journal articles are more authoritative.

Determining what sources are reliable can be challenging. Peer-reviewed scholarly journal articles are the gold standard in academic research. Reputable academic journals have a rigorous peer-review process.

The peer review process provides accountability to the academic community, as well as to the content of the article. The peer review process involves qualified experts in a specific (often very specific) field performing a review of an article's methods and findings to determine things like quality and credibility.

Peer-reviewed articles can be found in peer-reviewed article databases and research databases, and if you know that a database of journals is reliable, that can offer reassurances about the reliability of a free article. Peer review is often double blind, meaning that the author removes all identifying information and, likewise, does not know the identity of the reviewers. This helps reviewers maintain objectivity and impartiality so as to judge an article based on its merit.

Where to Find Peer-Reviewed Articles

Peer-reviewed articles can be found in a variety of research databases. Below is a list of some of the major databases you can use to find peer-reviewed articles and other sources in disciplines spanning the humanities, sciences, and social sciences.

What Are Open Access Journals?

An open access (OA) journal is a journal whose content can be accessed without payment. This provides scholars, students, and researchers with free journal articles. OA journals use alternate methods of funding to cover publication costs so that articles can be published without having to pass those publication costs on to the reader.

Some of these funding models include standard funding methods like advertising, public funding, and author payment models, where the author pays a fee in order to publish in the journal. There are OA journals that have non-peer-reviewed academic content, as well as journals that focus on dissertations, theses, and papers from conferences, but the main focus of OA is peer-reviewed scholarly journal articles.

The internet has certainly made it easier to access research articles and other scholarly publications without needing access to a university library, and OA takes another step in that direction by removing financial barriers to academic content.

Choosing Wisely

Features of legitimate oa journals.

 There are things to look out for when trying to decide if a free publication journal is legitimate:

Mission statement —The mission statement for an OA journal should be available on their website.

Publication history —Is the journal well established? How long has it been available?

Editorial board —Who are the members of the editorial board, and what are their credentials?

Indexing —Can the journal be found in a reliable database?

Peer review —What is the peer review process? Does the journal allow enough time in the process for a reliable assessment of quality?

Impact factor —What is the average number of times the journal is cited over a two-year period?

Features of Illegitimate OA Journals

There are predatory publications that take advantage of the OA format, and they are something to be wary of. Here are some things to look out for:

Contact information —Is contact information provided? Can it be verified?

Turnaround —If the journal makes dubious claims about the amount of time from submission to publication, it is likely unreliable.

Editorial board —Much like determining legitimacy, looking at the editorial board and their credentials can help determine illegitimacy.

Indexing —Can the journal be found in any scholarly databases?

Peer review —Is there a statement about the peer review process? Does it fit what you know about peer review?

How to Find Scholarly Articles

Identify keywords.

Keywords are included in an article by the author. Keywords are an excellent way to find content relevant to your research topic or area of interest. In academic searches, much like you would on a search engine, you can use keywords to navigate through what is available to find exactly what you're looking for.

Authors provide keywords that will help you easily find their article when researching a related topic, often including general terms to accommodate broader searches, as well as some more specific terms for those with a narrower scope. Keywords can be used individually or in combination to refine your scholarly article search.

Narrow Down Results

Sometimes, search results can be overwhelming, and searching for free articles on a journal database is no exception, but there are multiple ways to narrow down your results. A good place to start is discipline.

What category does your topic fall into (psychology, architecture, machine learning, etc.)? You can also narrow down your search with a year range if you're looking for articles that are more recent.

A Boolean search can be incredibly helpful. This entails including terms like AND between two keywords in your search if you need both keywords to be in your results (or, if you are looking to exclude certain keywords, to exclude these words from the results).

Consider Different Avenues

If you're not having luck using keywords in your search for free articles, you may still be able to find what you're looking for by changing your tactics. Casting a wider net sometimes yields positive results, so it may be helpful to try searching by subject if keywords aren't getting you anywhere.

You can search for a specific publisher to see if they have OA publications in the academic journal database. And, if you know more precisely what you're looking for, you can search for the title of the article or the author's name.

Determining the Credibility of Scholarly Sources

Ensuring that sources are both credible and reliable is crucial to academic research. Use these strategies to help evaluate the usefulness of scholarly sources:

• Peer Review : Look for articles that have undergone a rigorous peer-review process. Peer-reviewed articles are typically vetted by experts in the field, ensuring the accuracy of the research findings.

Tip: To determine whether an article has undergone rigorous peer review, review the journal's editorial policies, which are often available on the journal's website. Look for information about the peer-review process, including the criteria for selecting reviewers, the process for handling conflicts of interest, and any transparency measures in place.

• Publisher Reputation : Consider the reputation of the publisher. Established publishers, such as well-known academic journals, are more likely to adhere to high editorial standards and publishing ethics.
• Author Credentials : Evaluate the credentials and expertise of the authors. Check their affiliations, academic credentials, and past publications to assess their authority in the field.
• Citations and References : Examine the citations and references provided in the article. A well-researched article will cite credible sources to support its arguments and findings. Verify the accuracy of the cited sources and ensure they are from reputable sources.
• Publication Date : Consider the publication date of the article. While older articles may still be relevant, particularly in certain fields, it is best to prioritize recent publications for up-to-date research and findings.
• Journal Impact Factor : Assess the journal's impact factor or other metrics that indicate its influence and reputation within the academic community. Higher impact factor journals are generally considered more prestigious and reliable. 

Tip: Journal Citation Reports (JCR), produced by Clarivate Analytics, is a widely used source for impact factor data. You can access JCR through academic libraries or directly from the Clarivate Analytics website if you have a subscription.

• Peer Recommendations : Seek recommendations from peers, mentors, or professors in your field. They can provide valuable insights and guidance on reputable sources and journals within your area of study.
• Cross-Verification : Cross-verify the information presented in the article with other credible sources. Compare findings, methodologies, and conclusions with similar studies to ensure consistency and reliability.

By employing these strategies, researchers can confidently evaluate the credibility and reliability of scholarly sources, ensuring the integrity of their research contributions in an ever-evolving landscape.

How to find peer-reviewed articles.

There are a lot of free scholarly articles available from various sources. The internet is a big place. So how do you go about finding peer-reviewed articles when conducting your research? It's important to make sure you are using reputable sources.

The first source of the article is the person or people who wrote it. Checking out the author can give you some initial insight into how much you can trust what you’re reading. Looking into the publication information of your sources can also indicate whether the article is reliable.

Aspects of the article, such as subject and audience, tone, and format, are other things you can look at when evaluating whether the article you're using is valid, reputable, peer-reviewed material. So, let's break that down into various components so you can assess your research to ensure that you're using quality articles and conducting solid research.

Check the Author

Peer-reviewed articles are written by experts or scholars with experience in the field or discipline they're writing about. The research in a peer-reviewed article has to pass a rigorous evaluation process, so it's a foregone conclusion that the author(s) of a peer-reviewed article should have experience or training related to that research.

When evaluating an article, take a look at the author's information. What credentials does the author have to indicate that their research has scholarly weight behind it? Finding out what type of degree the author has—and what that degree is in—can provide insight into what kind of authority the author is on the subject.

Something else that might lend credence to the author's scholarly role is their professional affiliation. A look at what organization or institution they are affiliated with can tell you a lot about their experience or expertise. Where were they trained, and who is verifying their research?

Identify Subject and Audience

The ultimate goal of a study is to answer a question. Scholarly articles are also written for scholarly audiences, especially articles that have gone through the peer review process. This means that the author is trying to reach experts, researchers, academics, and students in the field or topic the research is based on.

Think about the question the author is trying to answer by conducting this research, why, and for whom. What is the subject of the article? What question has it set out to answer? What is the purpose of finding the information? Is the purpose of the article of importance to other scholars? Is it original content?

Research should also be approached analytically. Is the methodology sound? Is the author using an analytical approach to evaluate the data that they have obtained? Are the conclusions they've reached substantiated by their data and analysis? Answering these questions can reveal a lot about the article's validity.

Format Matters

Reliable articles from peer-reviewed sources have certain format elements to be aware of. The first is an abstract. An abstract is a short summary or overview of the article. Does the article have an abstract? It's unlikely that you're reading a peer-reviewed article if it doesn't. Peer-reviewed journals will also have a word count range. If an article seems far too short or incredibly long, that may be reason to doubt it.

Another feature of reliable articles is the sections the information is divided into. Peer-reviewed research articles will have clear, concise sections that appropriately organize the information. This might include a literature review, methodology, results (in the case of research articles), and a conclusion.

One of the most important sections is the references or bibliography. This is where the researcher lists all the sources of their information. A peer-reviewed source will have a comprehensive reference section.

An article that has been written to reach an academic community will have an academic tone. The language that is used, and the way this language is used, is important to consider. If the article is riddled with grammatical errors, confusing syntax, and casual language, it almost definitely didn't make it through the peer review process.

Also consider the use of terminology. Every discipline is going to have standard terminology or jargon that can be used and understood by other academics in the discipline. The language in a peer-reviewed article is going to reflect that.

If the author is going out of their way to explain simple terms, or terms that are standard to the field or discipline, it's unlikely that the article has been peer reviewed, as this is something that the author would be asked to address during the review process.

Publication

The source of the article will be a very good indicator of the likelihood that it was peer reviewed. Where was the article published? Was it published alongside other academic articles in the same discipline? Is it a legitimate and reputable scholarly publication?

A trade publication or newspaper might be legitimate or reputable, but it is not a scholarly source, and it will not have been subject to the peer review process. Scholarly journals are the best resource for peer-reviewed articles, but it's important to remember that not all scholarly journals are peer reviewed.

It's helpful to look at a scholarly source's website, as peer-reviewed journals will have a clear indication of the peer review process. University libraries, institutional repositories, and reliable databases (and now you have a list of legit ones) can also help provide insight into whether an article comes from a peer-reviewed journal.

Common Research Mistakes to Avoid

Research is a lot of work. Even with high standards and good intentions, it's easy to make mistakes. Perhaps you searched for access to scientific journals for free and found the perfect peer-reviewed sources, but you forgot to document everything, and your references are a mess. Or, you only searched for free online articles and missed out on a ground-breaking study that was behind a paywall.

Whether your research is for a degree or to get published or to satisfy your own inquisitive nature, or all of the above, you want all that work to produce quality results. You want your research to be thorough and accurate.

To have any hope of contributing to the literature on your research topic, your results need to be high quality. You might not be able to avoid every potential mistake, but here are some that are both common and easy to avoid.

Sticking to One Source

One of the hallmarks of good research is a healthy reference section. Using a variety of sources gives you a better answer to your question. Even if all of the literature is in agreement, looking at various aspects of the topic may provide you with an entirely different picture than you would have if you looked at your research question from only one angle.

Not Documenting Every Fact

As you conduct your research, do yourself a favor and write everything down. Everything you include in your paper or article that you got from another source is going to need to be added to your references and cited.

It's important, especially if your aim is to conduct ethical, high-quality research, that all of your research has proper attribution. If you don't document as you go, you could end up making a lot of work for yourself if the information you don't write down is something that later, as you write your paper, you really need.

Using Outdated Materials

Academia is an ever-changing landscape. What was true in your academic discipline or area of research ten years ago may have since been disproven. If fifteen studies have come out since the article that you're using was published, it's more than a little likely that you're going to be basing your research on flawed or dated information.

If the information you're basing your research on isn't as up-to-date as possible, your research won't be of quality or able to stand up to any amount of scrutiny. You don't want all of your hard work to be for naught.

Relying Solely on Open Access Journals

OA is a great resource for conducting academic research. There are high-quality journal articles available through OA, and that can be very helpful for your research. But, just because you have access to free articles, that doesn't mean that there's nothing to be found behind a paywall.

Just as dismissing high-quality peer-reviewed articles because they are OA would be limiting, not exploring any paid content at all is equally short-sighted. If you're seeking to conduct thorough and comprehensive research, exploring all of your options for quality sources is going to be to your benefit.

Digging Too Deep or Not Deep Enough

Research is an art form, and it involves a delicate balance of information. If you conduct your research using only broad search terms, you won't be able to answer your research question well, or you'll find that your research provides information that is closely related to your topic but, ultimately, your findings are vague and unsubstantiated.

On the other hand, if you delve deeply into your research topic with specific searches and turn up too many sources, you might have a lot of information that is adjacent to your topic but without focus and perhaps not entirely relevant. It's important to answer your research question concisely but thoroughly.

Different Types of Scholarly Articles

Different types of scholarly articles have different purposes. An original research article, also called an empirical article, is the product of a study or an experiment. This type of article seeks to answer a question or fill a gap in the existing literature.

Research articles will have a methodology, results, and a discussion of the findings of the experiment or research and typically a conclusion.

Review articles overview the current literature and research and provide a summary of what the existing research indicates or has concluded. This type of study will have a section for the literature review, as well as a discussion of the findings of that review. Review articles will have a particularly extensive reference or bibliography section.

Theoretical articles draw on existing literature to create new theories or conclusions, or look at current theories from a different perspective, to contribute to the foundational knowledge of the field of study.

10 Tips for Navigating Journal Databases

Use the right academic journal database for your search, be that interdisciplinary or specific to your field. Or both!

If it's an option, set the search results to return only peer-reviewed sources.

Start by using search terms that are relevant to your topic without being overly specific.

Try synonyms, especially if your keywords aren't returning the desired results.

Even if you've found some good articles, try searching using different terms.

Explore the advanced search features of the database(s).

Learn to use Booleans (AND, OR, NOT) to expand or narrow your results.

Once you've gotten some good results from a more general search, try narrowing your search.

Read through abstracts when trying to find articles relevant to your research.

Keep track of your research and use citation tools. It'll make life easier when it comes time to compile your references.

7 Frequently Asked Questions

1. how do i get articles for free.

Free articles can be found through free online academic journals, OA databases, or other databases that include OA journals and articles. These resources allow you to access free papers online so you can conduct your research without getting stuck behind a paywall.

Academics don't receive payment for the articles they contribute to journals. There are often, in fact, publication fees that scholars pay in order to publish. This is one of the funding structures that allows OA journals to provide free content so that you don't have to pay fees or subscription costs to access journal articles.

2. How Do I Find Journal Articles?

Journal articles can be found in databases and institutional repositories that can be accessed at university libraries. However, online research databases that contain OA articles are the best resource for getting free access to journal articles that are available online.

Peer-reviewed journal articles are the best to use for academic research, and there are a number of databases where you can find peer-reviewed OA journal articles. Once you've found a useful article, you can look through the references for the articles the author used to conduct their research, and you can then search online databases for those articles, too.

3. How Do I Find Peer-Reviewed Articles?

Peer-reviewed articles can be found in reputable scholarly peer-reviewed journals. High-quality journals and journal articles can be found online using academic search engines and free research databases. These resources are excellent for finding OA articles, including peer-reviewed articles.

OA articles are articles that can be accessed for free. While some scholarly search engines and databases include articles that aren't peer reviewed, there are also some that provide only peer-reviewed articles, and databases that include non-peer-reviewed articles often have advanced search features that enable you to select "peer review only." The database will return results that are exclusively peer-reviewed content.

4. What Are Research Databases?

A research database is a list of journals, articles, datasets, and/or abstracts that allows you to easily search for scholarly and academic resources and conduct research online. There are databases that are interdisciplinary and cover a variety of topics.

For example, Paperity might be a great resource for a chemist as well as a linguist, and there are databases that are more specific to a certain field. So, while ERIC might be one of the best educational databases available for OA content, it's not going to be one of the best databases for finding research in the field of microbiology.

5. How Do I Find Scholarly Articles for Specific Fields?

There are interdisciplinary research databases that provide articles in a variety of fields, as well as research databases that provide articles that cater to specific disciplines. Additionally, a journal repository or index can be a helpful resource for finding articles in a specific field.

When searching an interdisciplinary database, there are frequently advanced search features that allow you to narrow the search results down so that they are specific to your field. Selecting "psychology" in the advanced search features will return psychology journal articles in your search results. You can also try databases that are specific to your field.

If you're searching for law journal articles, many law reviews are OA. If you don't know of any databases specific to history, visiting a journal repository or index and searching "history academic journals" can return a list of journals specific to history and provide you with a place to begin your research.

6. Are Peer-Reviewed Articles Really More Legitimate?

The short answer is yes, peer-reviewed articles are more legitimate resources for academic research. The peer review process provides legitimacy, as it is a rigorous review of the content of an article that is performed by scholars and academics who are experts in their field of study. The review provides an evaluation of the quality and credibility of the article.

Non-peer-reviewed articles are not subject to a review process and do not undergo the same level of scrutiny. This means that non-peer-reviewed articles are unlikely, or at least not as likely, to meet the same standards that peer-reviewed articles do.

7. Are Free Article Directories Legitimate?

Yes! As with anything, some databases are going to be better for certain requirements than others. But, a scholarly article database being free is not a reason in itself to question its legitimacy.

Free scholarly article databases can provide access to abstracts, scholarly article websites, journal repositories, and high-quality peer-reviewed journal articles. The internet has a lot of information, and it's often challenging to figure out what information is reliable. 

Research databases and article directories are great resources to help you conduct your research. Our list of the best research paper websites is sure to provide you with sources that are totally legit.

Open research reports

JSTOR hosts a growing curated collection of more than 50,000 open research reports from 187 think tanks and research institutes from around the world. These publications are freely accessible to everyone on JSTOR and discoverable as their own content type alongside journals, books, and primary sources. We update research reports on our platform each month as they become available through contributing institutes.

Download the list (xlsx) of contributing policy institutes.

Research reports provide current analysis on many of today’s most discussed and debated issues from a diversity of ideological and international perspectives representing 40 countries and 29 languages. A sample of topics would include: climate change, border security, fake news, cybersecurity, electric vehicles, artificial intelligence, energy policy, gender issues, terrorism, remote learning, recent trends in business and economics, and various public health issues, including COVID-19.

Although the briefs, papers, and reports published by these institutes are not peer-reviewed, they are written by policy experts and members of the academic community who are fellows in residence. This is content that impacts policy, both foreign and domestic. It is also increasingly used by faculty in their classrooms for its currency, breadth, and accessibility.

JSTOR’s research reports cover seven Areas of Focus: Business & Economics, Critical Race & Ethnic Studies, Education, Gender & Sexuality, Public Health, Security Studies, and Sustainability.

Why research reports on JSTOR?

Input from faculty and librarians revealed that although research reports were for the most part freely available outside of JSTOR, they were hard to find and not easily discoverable alongside relevant material. It was also difficult for students to differentiate between the most credible research reports and a growing corpus of questionable sources on the Web.

JSTOR has attempted to redress these issues by centralizing a curated collection of think tank research reports on a single platform, making this content freely available to all JSTOR users, and enhancing its discoverability through comprehensive searching and the application of rich metadata.

Sci-Hub is the most controversial project in today science. The goal of Sci-Hub is to provide free and unrestricted access to all scientific knowledge ever published in journal or book form.

Today the circulation of knowledge in science is restricted by high prices. Many students and researchers cannot afford academic journals and books that are locked behind paywalls. Sci-Hub emerged in 2011 to tackle this problem. Since then, the website has revolutionized the way science is being done.

Sci-Hub is helping millions of students and researchers, medical professionals, journalists and curious people in all countries to unlock access to knowledge. The mission of Sci-Hub is to fight every obstacle that prevents open access to knowledge: be it legal, technical or otherwise.

5 free and legal ways to get the full text of research articles

By Carol Hollier on 07-Apr-2021 13:23:17

1.  Use your library if you have one !

If you are affiliated with a university, you probably have free library access to the full text of millions of research articles.   The library will have subscribed to these journals on your behalf. The smartest thing you can do for accessing research articles is familiarize yourself with your own library.

• If you search a database your library will link from the records to the full text if they have it—all you need to do is click through the links.
• When they do not have a copy of an article, a university library can get it for you from another library. This inter-library loan service is usually free to users.
• Your library might use a browser extension like Lean Library or LibKey Nomad to link you to the library subscription or open access full text from wherever you are on the internet.
• Google Scholar lets you configure your account to get links straight to your library’s subscription copy of an article.  But remember--side-by-side to library subscriptions for legitimate research, Google Scholar includes links to articles published in predatory and unreliable journals that would be unwise to credit in your own work.  Learn more about predatory journals.

If you are not affiliated with a university library, there are still ways you can successfully—and legally—get the full text of research articles.

2.  Open Access browser extensions  

More and more research is published Open Access as governments around the world are mandating that research paid for by taxpayer money be freely available to those taxpayers.

Browser extensions have been created to make it easy to spot when the full text of an article is free.   Some of the best are CORE Discovery , Unpaywall and Open Access Button .

Learn more about difference between discovery and access and why it matters for good research: Where to search - Best Practice for Literature Searching - LibGuides at IFIS

3. Google Scholar

You can search the article title inside quotation marks on Google Scholar to see if a link to a copy of the article appears.   If it does, be sure to pay attention to what version of the article you are linking to, to be sure you are getting what you think you’re getting.  These links can lead to an article's published version of record, a manuscript version, or to a thesis or conference proceeding with the same title and author as the article you expected to find.   

4.  Researcher platforms

 A Google Scholar search might lead you to a researcher platform like Academia.edu or ResearchGate .   There, if you set up an account, you can sometimes download or request a copy of the text.  Again, pay attention to which version of the text you get!

5.  Write to the author

If you can’t get a copy by other means, you can write to an article’s corresponding author and (politely!) ask them to send you a copy. Their contact information, usually an email address, will be listed in the information you find about the article, either in a database record for the article or on the publishing journal’s page for it. Many authors are happy to share a copy of their work.

Three bonus ways that might work depending on where you live:

1.  A nearby university library might offer access to articles even if you do not work or study there.

Members of the public are sometimes allowed access to university journal subscriptions through visitor access or a walk-in user service. You usually need to use the collections from a dedicated computer terminal located in a library and may need to make an appointment before you go. Do your research before showing up to make sure you bring the correct documents and equipment (like a flash drive) along.

2.  Try your public library

In some countries, public libraries partner with publishers to give the public access to research articles.   In the UK, for instance, many public libraries participate in the Access to Research scheme, which gives members of the public on-site access to over 30 million academic articles. Contact your local public library to learn what is available to you.

3.  Research4Life

In other countries, your institution might have access to a massive collection of research articles and databases through the publisher/library/United Nations agency initiative Research4Life . Check to see if you already have access, and if not, if your institution might be eligible to join. Membership is only available on an organizational or institutional level.  

Remember —even though you now have a lot of strategies for finding the full text of articles, research should never be led by the articles you can access most easily.

Good research is driven by first figuring out what articles are most relevant to your question and then getting the full text of what you need. One of the best ways to do this is to use a good discipline-specific database, like FSTA for the sciences of food and health.

10 Free Research and Journal Databases

3-minute read

• 6th April 2019

Finding good research can be tough, especially when so much of it is locked behind paywalls . But there are free resources out there if you know where to look. So to help out, we’ve compiled a list of ten free academic search engines and databases that you should check out.

1. Google Scholar

Even if you’ve not used Google Scholar before, you’ll know Google. And, thus, you can probably guess that Google Scholar is a search engine dedicated to academic work. Not everything listed on Google Scholar will be freely available in full. But it is a good place to start if you’re looking for a specific paper, and many papers can be downloaded for free.

CORE is an open research aggregator. This means it works as a search engine for open access research published by organizations from around the world, all of which is available for free. It is also the world’s largest open access aggregator , so it is a very useful resource for researchers!

3. Bielefeld Academic Search Engine (BASE)

Another dedicated academic search engine, BASE offers access to more than 140 million documents from more than 6,000 sources. Around 60% of these documents are open access, and you can filter results to see only research that is available for free online.

4. Directory of Open Access Journals (DOAJ)

The Directory of Open Access Journals (DOAJ) is a database that lists around 12,000 open access journals covering all areas of science, technology, medicine, social science, and the humanities.

PubMed is a search engine maintained by the NCBI, part of the United States National Library of Medicine. It provides access to more than 29 million citations of biomedical research from MEDLINE, life science journals, and online books. The NCBI runs a similar search engine for research in the chemical sciences called PubChem , too, which is also free to use.

6. E-Theses Online Service (EThOS)

Run by the British Library, EThOS is a database of over 500,000 doctoral theses. More than half of these are available for free, either directly via EThOS or via a link to a university website.

7. Social Science Research Network (SSRN)

SSRN is a database for research from the social sciences and humanities, including 846,589 research papers from 426,107 researchers across 30 disciplines. Most of these are available for free, although you may need to sign up as a member (also free) to access some services.

8. WorldWideScience

WorldWideScience is a global academic search engine, providing access to national and international scientific databases from across the globe. One interesting feature is that it offers automatic translation, so users can have search results translated into their preferred language.

9. Semantic Scholar

Semantic Scholar is an “intelligent” academic search engine. It uses machine learning to prioritize the most important research, which can make it easier to find relevant literature. Or, in Semantic Scholar’s own words, it uses influential citations, images, and key phrases to “cut through the clutter.”

10. Public Library of Science (PLOS)

PLOS is an open-access research organization that publishes several journals. But as well as publishing its own research, PLOS is a dedicated advocate for open-access learning. So if you appreciate the search engines and databases we’ve listed here, check out the rest of the PLOS site to find out more about their campaign to enable access to knowledge.

How to Find Free Articles on Google Scholar

There are tons of resources for students to find articles online, and Google Scholar is a top pick. Here's how to use it.

Are you working on a research project or simply looking for credible information? Google Scholar can help you find free and credible research articles.

Instead of searching for scholarly articles in a standard Google search, you can use a simpler method to find articles. Google Scholar is a division of Google that focuses on scholarly literature, that way you can easily find articles that you need for your research.

Find Free Articles on Google Scholar

You might enjoy reading insanely weird articles on Wikipedia . However, maybe it's time that you read information from the academics that the world has to offer.

It can be frustrating searching the internet for articles, without finding anything that doesn't require payment. Google Scholar offers a wide variety of research articles, many of which are available for free.

Here's how to find free articles on Google Scholar:

• Head to Google Scholar .
• Type out a keyword search in the search bar.
• When the results are displayed, only check for articles with a PDF text link.
• Click on the link for your desired article.
• Check if the article has a free downloadable link, or if you can read it for free online.
• Once you have found a free article, save the PDF document onto your device or read it online.

Typically, free articles on Google Scholar have a visible PDF text link next to the article title. If you are unlucky, the link will lead you to the publisher's website, where you would have to purchase the article.

However, when the article is free, you can save the document or read it online.

Finding Recently Published Articles

Google Scholar allows you to filter your search to a specific time frame. This way, you can find articles that were recently published, or that were published over 5 to 10 years ago.

To find an article according to the year it was published, click Since Year on Google Scholar's left sidebar. This allows you to find article papers that were published from the specified year. You can also choose whether you want the results page on Google Chrome to sort articles by date or relevance.

Improve Your Research Skills

Knowing how to research effectively is not an easy skill to have. Luckily, the internet makes life easier in so many ways. One of those ways is helping you research better.

If you are a research student, you might want to find out how to make the most of your search browser. That way you can get the best results from your research.

Open Access

Open Access is the free, immediate, online availability of research articles coupled with the rights to use these articles fully in the digital environment. Open Access ensures that anyone can access and use these results—to turn ideas into industries and breakthroughs into better lives.

Research provides the foundation of modern society. Research leads to breakthroughs, and communicating the results of research is what allows us to turn breakthroughs into better lives—to provide new treatments for disease, to implement solutions for challenges like global warming, and to build entire industries around what were once just ideas.

However, our current system for communicating research is crippled by a centuries old model that hasn’t been updated to take advantage of 21st century technology:

• Governments provide most of the funding for research—hundreds of billions of dollars annually—and public institutions employ a large portion of all researchers.
• Researchers publish their findings without the expectation of compensation. Unlike other authors, they hand their work over to publishers without payment, in the interest of advancing human knowledge.
• Through the process of peer review, researchers review each other’s work for free.
• Once published, those that contributed to the research (from taxpayers to the institutions that supported the research itself) have to pay again to access the findings. Though research is produced as a public good, it isn’t available to the public who paid for it.

Our current system for communicating research uses a print-based model in the digital age. Even though research is largely produced with public dollars by researchers who share it freely, the results are hidden behind technical, legal, and financial barriers. These artificial barriers are maintained by legacy publishers and restrict access to a small fraction of users, locking out most of the world’s population and preventing the use of new research techniques.

This fundamental mismatch between what is possible with digital technology—an open system for communicating research results in which anyone, anywhere can contribute—and our outdated publishing system has led to the call for Open Access.

Open Access is the free, immediate, online availability of research articles combined with the rights to use these articles fully in the digital environment. Open Access is the needed modern update for the communication of research that fully utilizes the Internet for what it was originally built to do—accelerate research.

Funders invest in research to advance human knowledge and ultimately improve lives. Open Access increases the return on that investment by ensuring the results of the research they fund can be read and built on by anyone.

Breakthroughs often come from unexpected places ; the Theory of Relativity was developed by a patent clerk. Open Access expands the number of potential contributors to research from just those at institutions wealthy enough to afford journal subscriptions to anyone with an internet connection.

Researchers benefit from having the widest possible audience. Researchers provide their articles to publishers for free, because their compensation comes in the form of recognition for their findings. Open Access means more readers, more potential collaborators, more citations for their work, and ultimately more recognition.

The research enterprise itself benefits when the latest techniques can be easily used. For years, we have had powerful text and data mining tools that can analyze the entire research literature, uncovering trends and connections that no human reader could. While publishers’ technical and legal barriers currently prevent their widespread use, Open Access empowers anyone to use these tools, which hold the potential of revolutionizing how research is conducted.

Even the best ideas remain just that until they are shared, until they can be utilized by others. The more people that can access and build upon the latest research, the more valuable that research becomes and the more likely we are to benefit as a society. More eyes make for smaller problems.

Harvard Library Is Launching Harvard Open Journals Program

Harvard Library is launching a new initiative called the Harvard Open Journals Program (HOJP), which will help researchers advance scholarly publishing that is open access, sustainable, and equitable. HOJP will provide publishing services, resources, and seed funding to participating Harvard researchers for new academic journals. All journal articles will be entirely free for authors and readers, with no barriers to publish or to access.

Martha Whitehead, Vice President for the Harvard Library and University Librarian, sees the initiative as an important step in championing open access. Whitehead said, “We want to model the original ethos of open access by reducing barriers and enabling the free flow of ideas and knowledge across the research ecosystem and beyond to the public at large.”

The Harvard Open Journals Program will offer publishing and hosting services to help the Harvard community launch new open access journals, or to convert existing journals to open access. The program will offer two support models: an overlay model which takes advantage of open access repositories, such as Harvard’s  DASH , and a brand-new academic press model. 

Yuan Li, University Scholarly Communication Officer and Director of Open Scholarship and Research Data Services at Harvard Library, pointed out the innovative nature of the program, “It is new for an institution to support faculty in seeking out an academic press to publish a no-fee open access journal and to provide assistance in securing its long-term funding. And offering a repository overlay journal model provides an alternative that appeals to some editorial boards and is gaining traction through initiatives such as Episciences. As we implement and refine this program on our campus, we hope it will inspire other universities to adopt such approaches to supporting barrier-free scholarly publishing.”

The program is a direct response to faculty interest in alternatives to the article-processing-charge model, in which journals charge author-side fees to publish papers open access. It also supports federal requirements that publications resulting from publicly-funded research be open access.

The open access movement in scholarly publishing seeks to grant free and public online access to publications and data. In recent decades, many researchers have become increasingly concerned that commercial rather than scholarly interests are driving the publishing ecosystem. With some publishers charging article processing fees of over $10,000 per article, skyrocketing costs inhibit many researchers and institutions from publishing in these journals. At the same time, research institutions continue to pay high subscription costs, even as their faculty provide editorial and peer review services mainly for free to the publishers. These practices have led to widespread outcry in the scholarly community, and tensions between publishers and editorial boards have led to the latter’s  mass resignations .

Scott Edwards, Professor of Organismic and Evolutionary Biology, and a member of the Harvard Library Faculty Advisory Council, applauds the library’s exploration of new models for supporting open access publishing. Edwards said, “In this increasingly challenging publishing ecosystem, the Harvard Open Journals Program is a welcome new approach.” 

“These are sustainable and equitable open access publishing models that allow scholars to take control of scholarly communication,” added Li. “I hope that many research-heavy institutions adopt our approach. The first  Harvard Open Access policy launched in 2008 has been adopted nationally and internationally, and it would be great to see similar reach.”

Under Harvard’s Open Access policies, Harvard faculty and researchers give the University a nonexclusive, irrevocable right to distribute their scholarly articles for any non-commercial purpose. Stored and preserved in  DASH , Harvard Library’s open access repository, these articles are made available to the scholarly community and the public—anyone with an internet connection can read them for free.

Harvard Library is working closely with the Office of the Vice Provost for Research on launching the HOJP program. John Shaw, Vice Provost for Research and Harry C. Dudley Professor of Structural and Economic Geology, is eager to promote the initiative in the suite of programs that support faculty research. Shaw said, “The launch of HOJP provides very encouraging options for removing barriers to making research results open and expanding their reach.”

The Harvard Open Journals Program will be open to all journals with a current Harvard affiliate on the editorial team or editorial board. Student-run journals are also eligible, as long as they are sponsored by a Harvard faculty member or administrator.

In preparing to launch HOJP this summer, Harvard Library is currently seeking input on program details from interested faculty. HOJP will begin accepting applications in the fall from journals and editorial boards. Colleen Cressman, Librarian for Open Publishing, will manage the program and can be reached by email for more information.

References form the backbone of any medical literature. Presently, because of high inflation, it is very difficult for any library/organization/college to purchase all journals. The condition is even worse for an individual person, such as private practitioners. The solution lies in the free availability of full-text articles. Here, the authors share their experiences about the accessibility of free full-text articles.

INTRODUCTION

Presently, in India nearly 314 medical colleges are providing undergraduate medical education in the form of MBBS, 163 colleges are providing doctor of medicine in diploma in Dermatology,Venereology and Leprosy (DVL), and 84 colleges are providing diploma in DVL.[ 1 – 3 ] In addition to this, 27 hospitals are providing diplomate of national board in diploma in Venereology and Dermatology.[ 4 ] On comparing this data with number of research articles published, the latter stands in a mediocre situation. One of the important cause responsible for the relatively less number of research publication is unavailability of free full-text articles. Research works, published by most of the journals, are paid. Many of the undergraduates or postgraduate students may not be able to purchase these high-cost journals or articles. In addition to this, many researchers may not be willing to spend money on journals. These are some of the situations where free full-text articles come for rescue, but many of the beginners may not be familiar about how to search these articles. In addition, free full-text articles are the first choice for many of the postgraduate students for their dissertation.

HOW TO APPROACH

In addition to journals which are fully Open Access, there are few other journals which operate through subscriptions as mainstream journals do, but which offer open access to the electronic versions of their articles after a delay of usually a year, or selectively for individual articles, provided the authors have paid an additional charge to “open up” the articles.[ 5 ]

Free full-text articles can be approached in the following ways.

Medknow Publications

Medknow Publications publish nearly 150 journals. They provide free access to the electronic editions of their journals.[ 6 ] Researchers just have to open the site www.medknow.com , fill the key word they require, and search. Alternatively, they can visit the search option, available in most of their journals site through www.journalonweb.com , fill the key word, and search across multiple journals. At times, this site alone provides sufficient number of references required for the purpose. The important dermatological journals published by Medknow Publications are Indian Dermatology Online Journal, Indian Journal of Dermatology, Indian Journal of Dermatology, Venereology, and Leprology, Indian Journal of Sexually Transmitted Diseases and AIDS, International Journal of Trichology, and Journal of Cutaneous and Aesthetic Surgery.[ 7 ]

PubMed Central and PubMed

PubMed Central is the United States National Library of Medicine's digital archive of biomedical and life sciences journal literature which provides free access to the full text of articles.[ 8 ] To search for free full-text articles on PubMed Central, one has to visit the site http://www.ncbi.nlm.nih.gov/pmc/ , write the topic/author/journal title, and search across all articles.

PubMed is a database of citations and abstracts for articles from thousands of journals. PubMed does not include full-text journal articles.[ 9 ] It includes links to full-text articles at many journal web sites as well as to most of the articles in PubMed Central.[ 10 ] Here, articles can be searched on the site http://www.ncbi.nlm.nih.gov/pubmed . Search can be restricted to contents free on web by using filter your results and clicking free full text.[ 11 ]

Directory of Open Access Journals

The directory aims to cover all open access scientific and scholarly journals that use a quality control system to guarantee the content.[ 12 ] It provides articles from 439 medicinal journals. Among them, 21 are from dermatology.[ 13 ] It includes Anais Brasileiros de Dermatologia, BMC Dermatology, Case Reports in Dermatology, Clinical Dermatology, Clinical Medicine Insights: Dermatology, Clinical, Cosmetic and Investigational Dermatology, Dermatología Peruana, Dermatology Online Journal,th Dermatology Reports, Dermatology Research and Practice, Egyptian Dermatology Online Journal, Indian Journal of Dermatology, Indian Journal of Dermatology, Venereology and Leprology, The Internet Journal of Dermatology, Journal of Clinical and Experimental Dermatology Research, Journal of the Egyptian Women's Dermatologic Society, Open Dermatology Journal, Revista Argentina de Dermatología, Surgical and Cosmetic Dermatology, Turk Dermatoloji Dergisi, Turkderm.[ 14 ] The disadvantage of directory of open access journals is that few of these journals are in languages other than English. Here, articles can be searched on the site http://www.doaj.org .

Electronic Resources in Medicine Consortium and National Medical Library

Electronic Resources in Medicine Consortium (ERMED) and National Medical Library (NML) are an excellent platform for obtaining free of cost recent journal articles for its member colleges. There is no membership fees charged from the Government Medical Colleges and institutions. The private colleges and institutions have to make payment per site price for e-sources purchased by the consortium in every calendar year.[ 15 ] Membership of the college can be checked from the site http://www.nmlermed.in/members.htm or volunteers can contact their library to check the membership and to get the user name and password of the site www.ermed.jccc.in allotted to their college.[ 16 ] In 2009, the number of ERMED members increased from 40 to 72 Government Medical Colleges/Institutes across the country.[ 17 ] At present, it covers nearly 32 journals of dermatology. It includes Acta Dermatoveneorologica Alpina, Pannonica et Adriatica, Acta Dermatovenerologica Croatica, Advances in Skin and Wound Care, American Journal of Clinical Dermatology, American Journal of Dermatopathology, Archives of Dermatological Research, Archives of Dermatology,, Asian Journal of Dermatology, BMC Dermatology, Clinical, Cosmetic and Investigational Dermatology, Clinical Dermatology, Contact Dermatitis, Dermatologic Surgery, Dermatology, Dermatology Nursing, Dermatology Online Journal, Dermatology Times, Indian Journal of Dermatology, Indian Journal of Dermatology, Venereology and Leprology, International Journal of Dermatology, Internet Journal of Dermatology, Journal of Drugs in Dermatology, Journal of Investigative Dermatology, Journal of the European Academy of Dermatology and Venereology, Medicine, Open Dermatology Journal, Pediatric Dermatology, Rosacea Review, Skin and Allergy News, Skin Pharmacology and Physiology, Turkdem-Archives of the Turkish Dermatology and Venerology and Turkish Journal of Dermatology.[ 18 ]

Journal articles related to the topic can be searched easily after signing in at the site www.ermed.jccc.in , followed by clicking search database.

Google, Google Scholar, and Yahoo

Google ( http://www.google.com ) and Yahoo search ( http://www.search.yahoo.com ) are two of the world's most hit web pages and two largest web-based search engines.[ 19 ] Usually these are the first search site for any scholar. They provide links for both paid and free articles. The disadvantage associated with these sites is that additionally they provide materials that may not give scholarly information. Many articles are repeated also. But the catch is that one article which is paid at one web link may be free at another web link. Google Scholar ( http://www.scholar.google.com ) provides a simple way to broadly search for the relevant scholarly literature and research.[ 19 ]

The Cochrane Library

The Cochrane Library provides high-quality review articles. The Cochrane Database of Systematic Reviews has an impact factor of 5.653 of 2009.[ 20 ] Articles can be searched on the site http://www.thecochranelibrary.com/view/0/index.html .

Public Library of Science

Public library of science is a nonprofit organization of scientists and physicians committed to making the world's scientific and medical literature a freely available public resource.[ 21 ] Everything published on this site is freely available throughout the world, for researchers to read, download, copy, distribute, and use.[ 22 ] Articles can be searched here on the site http://www.plos.org/search.php .

Free Medical Journals

UK PubMed Central

UK PubMed Central (UKPMC) is a full-text article database that extends the functionality of the original PubMed Central (PMC) repository. UKPMC ( http://ukpmc.ac.uk ) has undergone considerable development since its inception in 2007 and now includes both a UKPMC and PubMed search, as well as access to other records such as Agricola, Patents, and recent biomedical theses. UKPMC also differs from PubMed/PMC in that the full text and abstract information can be searched in an integrated manner from one input box. All of the articles in UKPMC are “Free Access,” Not all content available in PMC is made available to UKPMC.[ 31 ]

The University of lowa libraries

How to write better ChatGPT prompts in 5 steps

ChatGPT is the generative artificial intelligence (AI) tool that's taken the world by storm. While there's always the possibility it will simply make stuff up , there's a lot you can do when crafting prompts to ensure the best possible outcome. That's what we'll be exploring in this how-to.

In this article, we'll show you how to write prompts that encourage the large language model (LLM) that powers  ChatGPT to provide the best possible answers. 

Also: Have 10 hours? IBM will train you in AI fundamentals - for free

Writing effective prompts, known as prompt engineering, has even become its own highly-paid discipline . Who knows? These tips could help you build the skills to become one of those highly paid prompt engineers. Apparently, these gigs can pay from $175,000 to $335,000 per year.  

How to write effective ChatGPT prompts

1. talk to the ai like you would a person.

One of the more interesting things I had to get used to when working with ChatGPT is that you don't program it, you talk to it. As a formally trained programmer, I've had to leave a lot of habits by the wayside when engaging with AI. Talking to it (and with it) requires a mindset shift.

When I say talk to it like a person, I mean talk to it like you would a co-worker or team member. If that's hard to do, give it a name. Alexa is taken, so maybe think of it as "Bob". This naming helps because when you talk to Bob, you might include conversational details, little anecdotes that give your story texture.

When talking to a person, it would be natural for them to miss your point initially and require clarification, or veer away from the topic at hand and need to be wrangled back. You might need to fill in the backstory for them, or restate complex questions based on the answers they give you. 

This is called interactive prompting. Don't be afraid to ask multi-step questions: ask, get a response, and based on that response, ask another question. I've done this myself, sometimes 10 or 20 times in a row, and gotten very powerful results. Think of this as having a conversation with ChatGPT.

2. Set the stage and provide context

Writing a ChatGPT prompt is more than just asking a one-sentence question. It often involves providing relevant background information to set the context of the query.

Let's say that you want to prepare for a marathon (for the record, I do not run, dance, or jump -- this is merely an example). You could ask ChatGPT:

How can I prepare for a marathon?

However, you'll get a far more nuanced answer if you add that you're training for your first marathon. Try this instead: 

I am a beginner runner and have never run a marathon before, but I want to complete one in six months. How can I prepare for a marathon?

By giving the AI more information, you're helping it return a more focused answer. Even with ChatGPT's help, there's no way I'm going to run a marathon (unless I'm doing it with a V-Twin motor under my seat). Here are two more examples of questions that provide context:

I am planning to travel to Spain in a few months and would like to learn some basic Spanish to help me communicate with local residents. I am looking for online resources that are suitable for beginners and provide a structured and comprehensive approach to learning the language. Can you recommend some online resources for learning Spanish as a beginner?

In this case, rather than just asking about learning resources, the context helps focus the AI on learning how to communicate on the ground with local residents. Here's another example: 

I am a business owner interested in exploring how blockchain technology can be used to improve supply chain efficiency and transparency. I am looking for a clear and concise explanation of the technology and examples of how it has been used in the context of supply chain management. Can you explain the concept of blockchain technology and its potential applications in supply chain management?

In this example, rather than just asking for information on blockchain and how it works, the focus is specifically on blockchain for supply chain efficiency and how it might be used in a real-world scenario. 

Also:  How to use Image Creator from Microsoft Designer (formerly Bing Image Creator) Lastly, let's get into how to construct a detailed prompt. 

One note: I limit the answer to 500 words because ChatGPT seems to break when asked to produce somewhere between 500 and 700 words, leaving stories mid-sentence and not resuming properly when asked to continue. I hope future versions provide longer answers, because premises like this can generate fun story beginnings: 

Write a short story for me, no more than 500 words. The story takes place in 2339, in Boston. The entire story takes place inside a Victorian-style bookstore that wouldn't be out of place in Diagon Alley. Inside the store are the following characters, all human: The proprietor: make this person interesting and a bit unusual, give them a name and at least one skill or characteristic that influences their backstory and possibly influences the entire short story. The helper: this is a clerk in the store. His name is Todd. The customer and his friend: Two customers came into the store together, Jackson and Ophelia. Jackson is dressed as if he's going to a Steampunk convention, while Ophelia is clearly coming home from her day working in a professional office. Another customer is Evangeline, a regular customer in the store, in her mid-40s. Yet another customer is Archibald, a man who could be anywhere from 40 to 70 years old. He has a mysterious air about himself and seems both somewhat grandiose and secretive. There is something about Archibald that makes the others uncomfortable. A typical concept in retail sales is that there's always more inventory "in the back," where there's a storeroom for additional goods that might not be shown on the shelves where customers browse. The premise of this story is that there is something very unusual about this store's "in the back." Put it all together and tell something compelling and fun.

You can see how the detail provides more for the AI to work with. First, feed "Write me a story about a bookstore" into ChatGPT and see what it gives you. Then feed in the above prompt and you'll see the difference.

3. Tell the AI to assume an identity or profession

One of ChatGPT's coolest features is that it can write from the point of view of a specific person or profession. In a previous article, I showed how you can make ChatGPT write like a pirate or Shakespeare , but you can also have it write like a teacher, a marketing executive, a fiction writer -- anyone you want. 

Also: How ChatGPT can rewrite and improve your existing code  

For example, I can ask ChatGPT to describe the Amazon Echo smart home device, but to do so from the point of view of a product manager, a caregiver, and a journalist in three separate prompts: 

From the point of view of its product manager, describe the Amazon Echo Alexa device. From the point of view of an adult child caring for an elderly parent, describe the Amazon Echo Alexa device. From the point of view of a journalist, describe the Amazon Echo Alexa device.

Try dropping these three prompts into ChatGPT to see its complete response. 

I've pulled a few lines from ChatGPT's responses, so you can see how it interprets different perspectives.  From the product manager identity:  I can confidently say that this is one of the most innovative and revolutionary products in the smart home industry.

From the caregiver identity:  The device's ability to set reminders and alarms can be particularly helpful for elderly individuals who may have trouble remembering to take their medication or attend appointments.

And from the journalist identity:  From a journalistic perspective, the Echo has made headlines due to privacy concerns surrounding the collection and storage of user data.

You can see how different identities allow the AI to provide different perspectives as part of its response. To expand this, you can let the AI do a thought experiment. Let's look at some of the issues that went into the creation of something like Alexa:

The year is 2012. Siri has been out for the iPhone for about a year, but nothing like an Alexa smart home device has been released. The scene is an Amazon board meeting where the Echo smart assistant based on Alexa has just been proposed.  Provide the arguments, pro and con, that board members at that meeting would have been likely to discuss as part of their process of deciding whether or not to approve spending to invest in developing the device.  Feel free to also include participation by engineering design experts and product champions, if that provides more comprehensive perspective.

It's also good to know that making minor changes to your prompts can significantly change ChatGPT's response. For example, when I changed the phrase, "Provide the arguments, pro and con, that..." to "Provide the pro and con arguments as dialogue, that...," ChatGPT rewrote its answer, switching from a list of enumerated pros and cons to an actual dialogue between participants.

4. Keep ChatGPT on track

As mentioned above, ChatGPT has a tendency to go off the rails, lose track of the discussion, or completely fabricate answers. 

There are a few techniques you can use to help keep it on track and honest.

One of my favorite things to do is ask ChatGPT to justify its responses. I'll use phrases like "Why do you think that?" or "What evidence supports your answer?" Often, the AI will simply apologize for making stuff up and come back with a new answer. Other times, it might give you some useful information about its reasoning path. In any case, don't forget to apply the tips I provide for having ChatGPT cite sources .

Also:  My two favorite ChatGPT Plus features and the remarkable things I can do with them

If you have a fairly long conversation with ChatGPT, you'll start to notice that the AI loses the thread. Not that that's unique to AIs -- even in extended conversations with humans, someone is bound to get lost. That said, you can gently guide the AI back on track by reminding it what the topic is, as well as what you're trying to explore.

5. Don't be afraid to play and experiment

One of the best ways to up your skill at this craft is to play around with what the chatbot can do.

Try feeding ChatGPT a variety of interesting prompts to see what it will do with them. Then change them up and see what happens. Here are five to get you started:

• Imagine you are a raindrop falling from the sky during a thunderstorm. Describe your journey from the moment you form in the cloud to the moment you hit the ground. What do you see, feel, and experience?
• You are a toy that has been left behind in an attic for decades. Narrate your feelings, memories of playtimes past, and your hopes of being rediscovered.
• Write the final diary entry of a time traveler who has decided to settle down in a specific era, explaining why they chose that time and what they've learned from their travels.
• Imagine a dialogue between two unlikely objects, like a teacup and a wristwatch, discussing the daily routines and challenges they face.
• Describe a day in an ant colony from the perspective of an ant. Dive deep into the politics, challenges, and social structures of the ant world.

Pay attention not only to what the AI generates, but how it generates what it does, what mistakes it makes, and where it seems to run into limits. All of that detail will help you expand your prompting horizons.

More prompt-writing tips 

• Feel free to re-ask the question. ChatGPT will often change its answer with each ask.
• Make small changes to your prompts to guide it into giving you a better answer.
• ChatGPT will retain its awareness of previous conversations as long as the current page is open. If you leave that page, it will lose awareness. To be clear, ChatGPT will also sometimes lose the thread of the conversation without reason, so be aware you may need to start over from time to time.
• Similarly, opening a new page will start the discussion with fresh responses.
• Be sure to specify the length of the response you want. Answers over about 500 words sometimes break down. 
• You can correct and clarify prompts based on how the AI answered previously. If it's misinterpreting you, you may be able to just tell it what it missed and continue.
• Rephrase questions if ChatGPT doesn't want to answer what you're asking. Use personas to elicit answers that it might not otherwise want to give.
• If you want sources cited , tell it to support or justify its answers.
• ChatGPT custom instructions are now available to free users. You can  give ChatGPT a set of prompts that are always available , so you don't have to retype them.
• Keep experimenting.
• Consider getting the ChatGPT Plus subscription . You can then use your own data for powerful analytics . You can also pull data from the Web . 
• Try asking the same question of Gemini  (formerly Bard) or Copilot (formerly Bing Chat). Both will interpret your prompts differently and answer differently. This is effectively getting a second opinion on your prompt, and can give you alternate perspectives.
• Ask for examples. If you want to see how well ChatGPT understands what you're asking for, ask it "Can you give me three examples of how that works?" or similar questions.
• Ask it to repeat parts of your original requests back to you. For example, if you feed it an article to analyze, you can tell it something like, "Just to be sure you understand, please echo back the first three headlines," or "I want to be sure you understand what I mean, so summarize the main conflict discussed in this article." 
• Sometimes ChatGPT just fails. Keep trying, but also be willing to give up and move on to other tools. It's not perfect...yet.

What type of prompts work best with ChatGPT? 

Part of what makes ChatGPT so compelling is you can ask it almost anything. That said, keep in mind that it's designed to provide written answers. If you want a list of websites, you're better off talking to Google. 

Also:  How to use DALL-E 3 in ChatGPT

If you want some form of computation, talk to Wolfram Alpha . Give ChatGPT open-ended prompts, encourage creativity, and don't be afraid to share personal experiences or emotions. Plus, keep in mind that the AI's knowledge ends in 2021  for ChatGPT 3.5 and December 2023 for ChatGPT 4 in ChatGPT Plus.

How can I adjust the complexity of ChatGPT responses?

You can directly specify the complexity level by including it in your prompt. Add "... at a high school level" or "... at a level intended for a Ph.D. to understand" to the end of your question. You can also increase complexity of output by increasing the richness of your input. The more you provide in your prompt, the more detailed and nuanced ChatGPT's response will be. You can also include other specific instructions, like "Give me a summary," "Explain in detail," or "Provide a technical description."

Also:  How does ChatGPT actually work?

You can also pre-define profiles. For example, you could say "When evaluating something for a manager, assume an individual with a four-year business college education, a lack of detailed technical understanding, and a fairly limited attention span, who likes to get answers that are clear and concise. When evaluating something for a programmer, assume considerable technical knowledge, an enjoyment of geek and science fiction references, and a desire for a complete answer. Accuracy is deeply important to programmers, so double-check your work."

If you ask ChatGPT to "explain C++ to a manager" and "explain C++ to a programmer," you'll see how the responses differ.

What do I do if ChatGPT refuses to answer or I don't like its answer? 

There are some guardrails built into ChatGPT. It tends to shut down if you ask it political questions, for example. That's what's built into the system. While you might be able to tease out an answer, it's probably not going to provide great value. That said, feel free to keep trying with different phrasing or perspectives.

Prime energy, sports drinks contain PFAS and excessive caffeine, class action suits say

YouTubers Logan Paul and KSI founded Prime Hydration in 2022, and while their products have become increasingly popular and profitable, the company continues to face class action suits over the ingredients in their energy and sports drinks.

Prime Hyrdation LLC was sued April 8 in the Southern District of New York over "misleading and deceptive practices" regarding the company's 12-ounce energy drinks containing between 215-225 milligrams of caffeine as opposed to the advertised 200 milligrams, according to the class action suit.

Lara Vera, a Poughkeepsie, New York resident, filed the suit in federal court on behalf of herself and others who bought Prime products across the U.S., the complaint says. Vera purchased Prime's Blue Raspberry products several times in August 2022 for about $3 to $4 each, but she would have never bought the drinks if she had known the actual caffeine content, according to the suit.

Vera's suit is seeking $5 million from the company owned by Paul and KSI, real name Olajide Olayinka Williams "JJ" Olatunji, court records show.

Court records do not say whether Prime Hydration retained legal counsel for Vera's suit.

How much caffeine is in Prime energy drinks?

Prime's advertised 200 milligrams of caffeine is equivalent to "half a dozen Coke cans or nearly two (12-ounce) Red Bulls," Vera's class action suit says.

A 12-ounce can of Red Bull energy drink contains 114 milligrams of caffeine, and a cup of coffee contains around 100 milligrams of caffeine, according to the suit.

The suit continues to say that "there is no proven safe dose of caffeine for children." Side effects of kids consuming caffeine could include rapid or irregular heartbeats, headaches, seizures, shaking, upset stomach and adverse emotional effects on mental health, according to the complaint.

Sen. Charles Schumer , D-N.Y., called on the Food and Drug Administration (FDA) to investigate Prime energy drinks in 2023 because of dangerously high caffeine levels. Schumer alleged in a letter to the FDA that vague marketing targeting young people influenced parents to buy a “cauldron of caffeine" for their kids.

Schumer's call to action to the FDA is referenced in Vera's suit.

USA TODAY contacted Prime Hydration's attorneys Tuesday afternoon but did not receive an immediate response.

What are the Prime Hydration lawsuits?

Vera's legal battle is beginning, but Prime is still dealing with another class action suit from 2023 alleging a flavor of the company's sports drinks contains PFAS, or "forever chemicals."

Independent third-party testing determined the presence of PFAS chemicals in Prime Hydration grape flavor, according to a class action suit filed Aug. 2, 2023, in the Northern District of California by the Milberg law firm on behalf of Elizabeth Castillo and others similarly affected.

"Lead plaintiff Elizabeth Castillo, a resident of California, purchased Prime Hydration on multiple occasions but says she would not have bought it at all if the product had been accurately marketed and labeled as containing PFAS," the Milberg law firm said in an August 2023 news release . "These chemicals were not reasonably detectible to consumers like herself."

Castillo's suit is seeking a $5 million judgment, court records show.

As of April 18, the judge in the case has heard Prime's argument to dismiss the suit due to Castillo not alleging "a cognizable injury" and her not alleging "facts showing a concrete (and) imminent threat of future harm," according to the drink company's motion.

Paul addressed Castillo's claims Wednesday in a 3-minute TikTok video.

"First off, anyone can sue anyone at any time that does not make the lawsuit true," Paul said in the TikTok video. "And in this case, it is not… one person conducted a random study and has provided zero evidence to substantiate any of their claims."

What are forever chemicals?

PFAS are called forever chemicals because they "bioaccumulate, or accrue in the body over time," the Milberg law said in its news release.

"These man-made chemicals are well-studied and have been found to have adverse effects on the human body and environment," the New York City-headquartered law firm said.

Many PFAS are found in people's and animal's blood and can be detected at low levels in a variety of food products and in the environment, the U.S. Environmental Protection Agency (EPA) said. Forever chemicals can be found in water, air, fish and soil at locations across the nation and the globe, according to the EPA.

"There are thousands of PFAS chemicals, and they are found in many different consumer, commercial, and industrial products," the EPA said. "This makes it challenging to study and assess the potential human health and environmental risks."

Who made Prime energy drinks?

Before founding Prime Hydration LLC, Logan Paul, 29, and KSI, 30, were YouTubers who turned their millions of subscribers into supporters of their boxing, wrestling, music, social media content and other endeavors.

Going into the drinks business proved to be profitable for both YouTubers as "Prime Hydration generated more than $250 million in retail sales in its first year, including $45 million in a single month," according to the Milberg law firm.

Paul and KSI continue to keep Prime products in the spotlight whether it is paying for an ad during Super Bowl 57 , having livestreamer IShowSpeed dress up in a Prime sports drink bottle during Wrestlemania 40 or signing athletes including Patrick Mahomes, Aaron Judge, Israel Adesanya, Tyreek Hill, Kyle Larson, Alisha Lehmann and others to sponsorship deals.

Moving Pictures: Transform Images Into 3D Scenes With NVIDIA Instant NeRF

Editor’s note: This post is part of the AI Decoded series , which demystifies AI by making the technology more accessible, and which showcases new hardware, software, tools and accelerations for RTX PC users.

Imagine a gorgeous vista, like a cliff along the water’s edge. Even as a 2D image, the scene would be beautiful and inviting. Now imagine exploring that same view in 3D – without needing to be there.

NVIDIA RTX technology-powered AI helps turn such an imagination into reality. Using Instant NeRF , creatives are transforming collections of still images into digital 3D scene s in just seconds.

Simply Radiant

A NeRF, or neural radiance field, is an AI model that takes 2D images representing a scene as input and interpolates between them to render a complete 3D scene. The model operates as a neural network — a model that replicates how the brain is organized and is often used for tasks that require pattern recognition.

Using spatial location and volumetric rendering, a NeRF uses the camera pose from the images to render a 3D iteration of the scene. Traditionally, these models are computationally intensive, requiring large amounts of rendering power and time.

A recent NVIDIA AI research project changed that.

Instant NeRF takes NeRFs to the next level, using AI-accelerated inverse rendering to approximate how light behaves in the real world. It enables researchers to construct a 3D scene from 2D images taken at different angles. Scenes can now be generated in seconds, and the longer the NeRF model is trained, the more detailed the resulting 3D renders.

NVIDIA researchers released four neural graphics primitives, or pretrained datasets, as part of the Instant-NGP training toolset at the SIGGRAPH computer graphics conference in 2022. The tools let anyone create NeRFs with their own data. The researchers won a best paper award for the work, and TIME Magazine named Instant NeRF a best invention of 2022 .

In addition to speeding rendering for NeRFs, Instant NeRF makes the entire image reconstruction process accessible using NVIDIA RTX and GeForce RTX desktop and laptop GPUs. While the time it takes to render a scene depends on factors like dataset size and the mix of image and video source content, the AI training doesn’t require server-grade or cloud-based hardware.

NVIDIA RTX workstations and GeForce RTX PCs are ideally suited to meet the computational demands of rendering NeRFs. NVIDIA RTX and GeForce RTX GPUs feature Tensor Cores, dedicated AI hardware accelerators that provide the horsepower to run generative AI locally.

Ready, Set, Go

Get started with Instant NeRF to learn about radiance fields and experience imagery in a new way.

Developers and tech enthusiasts can download the source-code base to compile. Nontechnical users can download the Windows installers for Instant-NGP software, available on GitHub .

While the installer is available for a wide range of RTX GPUs, the program performs best on the latest-architecture GeForce RTX 40 Series and NVIDIA RTX Ada Generation GPUs.

The “Getting Started With Instant NeRF” guide walks users through the process, including loading one of the primitives, such as “NeRF Fox,” to get a sense of what’s possible. Detailed instructions and video walkthroughs — like the one above — demonstrate how to create NeRFs with custom data, including tips for capturing good input imagery and compiling codebases (if built from source). The guide also covers using the Instant NeRF graphical user interface, optimizing scene parameters and creating an animation from the scene.

The NeRF community also offers many tips and tricks to help users get started. For example, check out the livestream below and this technical blog post .

Show and Tell

Digital artists are composing beautiful scenes and telling fresh stories with NVIDIA Instant NeRF. The Instant NeRF gallery showcases some of the most innovative and thought-provoking examples, viewable as video clips in any web browser.

Here are a few:

• “Through the Looking Glass” by Karen X. Cheng and James Perlman A pianist practices her song, part of her daily routine, though there’s nothing mundane about what happens next. The viewer peers into the mirror, a virtual world that can be observed but not traversed; it’s unreachable by normal means. Then, crossing the threshold, it’s revealed that this mirror is in fact a window into an inverted reality that can be explored from within. Which one is real?
• “Meditation” by Franc Lucent As soon as they walked into one of many rooms in Nico Santucci’s estate, Lucent knew they needed to turn it into a NeRF. Playing with the dynamic range and reflections in the pond, it presented the artist with an unknown exploration. They were pleased with the softness of the light and the way the NeRF elevates the room into what looks like something out of a dream — the perfect place to meditate. A NeRF can freeze a moment in a way that’s more immersive than a photo or video.
• “Zeus” by Hugues Bruyère These rendered 3D scenes with Instant NeRF use the data Bruyère previously captured for traditional photogrammetry using mirrorless digital cameras, smartphones, 360-degree cameras and drones. Instant NeRF gives him a powerful tool to help preserve and share cultural artifacts through online libraries, museums, virtual-reality experiences and heritage-conservation projects. This NeRF was trained using a dataset of photos taken with an iPhone at the Royal Ontario Museum.

From Image to Video to Reality

Transforming images into a 3D scene with AI is cool. Stepping into that 3D creation is next level.

Thanks to a recent Instant NeRF update, users can render their scenes from static images and virtually step inside the environments, moving freely within the 3D space. In virtual-reality (VR) environments, users can feel complete immersion into new worlds, all within their headsets.

The potential benefits are nearly endless.

For example, a realtor can create and share a 3D model of a property, offering virtual tours at new levels. Retailers can showcase products in an online shop, powered by a collection of images and AI running on RTX GPUs. These AI models power creativity and are helping drive the accessibility of 3D immersive experiences across other industries.

Instant NeRF comes with the capability to clean up scenes easily in VR, making the creation of high-quality NeRFs more intuitive than ever. Learn more about navigating Instant NeRF spaces in VR .
