How to find open-access research for free, legally

When a news story mentions a study, the original paper is often one click away and behind a paywall. Paying $30 or more to read one article isn't realistic for most parents or teachers. Fortunately a large share of research is available free and legally if you know where to look. This guide covers the main routes, roughly in the order we'd try them.

First, find the paper itself

You need something to search for. News stories vary in how much they give you. Look for:

• The title of the study, or a distinctive phrase from it.
• The journal name.
• The lead author's name and institution.
• A DOI, a string that starts with "10." and uniquely identifies the paper.

If the story only says "a new study from a major university", try the university's press office page. Press releases usually name the journal and authors, and often link to the paper.

Google Scholar

Google Scholar searches academic papers specifically. Type the title or the author's name and a few keywords. Two features help:

• A link on the right of a result, marked [PDF] or [HTML], often leads to a free copy.
• The "All versions" link under a result lists every copy Scholar has found, including ones in repositories and on authors' pages. If the first link is paywalled, check the others.

Scholar also shows "Cited by", which is a quick way to see whether later studies built on, or challenged, the one you're reading.

PubMed and PubMed Central

For anything touching health, development or medicine, the US National Library of Medicine runs two databases. PubMed indexes abstracts from biomedical journals. PubMed Central (PMC) holds free full texts.

Research funded by the US National Institutes of Health must be deposited in PMC. Under NIH's updated public access policy, papers accepted for publication from July 1, 2025 onward have to be made available there without the old 12-month delay. Many other funders around the world have similar rules. On a PubMed record, look for a "Free PMC article" label or a full-text link.

Unpaywall

Unpaywall is a free browser extension from the nonprofit OurResearch. When you land on a paywalled article page, a small tab appears if it has found a legal free version elsewhere; click it to go there. It only links to copies hosted legally, such as repositories and authors' pages. It's the single most useful tool in this guide for people who read papers occasionally.

Open-access journals

Some journals publish everything free to read. The Directory of Open Access Journals (DOAJ) lists those that meet its quality criteria, and you can search their articles directly.

Free to read doesn't mean lower quality, and a paywall doesn't mean higher quality. But some publishers, sometimes called predatory, charge authors fees and publish with little or no real review. Being listed in DOAJ is one reasonable sign that a journal isn't one of these.

Repositories and aggregators

Universities and research institutes run repositories where staff deposit their papers. You rarely need to search these one by one. CORE aggregates open-access papers from thousands of repositories worldwide, and Google Scholar's "All versions" picks many of them up too.

For education research specifically, ERIC, run by the US Department of Education's Institute of Education Sciences, indexes journal articles and reports, and many records include free full text. Filter for "full text available on ERIC".

Preprints

A preprint is a paper posted publicly before peer review. Servers such as PsyArXiv, SocArXiv, EdArXiv and medRxiv host many papers on child development, education and health. They're free and often appear months before the published version.

Read preprints with care. They haven't been checked by reviewers yet, and findings sometimes change before publication. Many preprint pages link to the published version if one exists, so check for that first.

Ask a librarian

Public libraries often subscribe to research databases you can use free with a library card, sometimes from home. University libraries may allow members of the public to read journals on site. Librarians are also very good at finding a specific article, and many offer help by email or chat.

Interlibrary loan can get a copy of an article your library doesn't hold, sometimes free.

Email the author

Researchers are generally happy to send a copy of their paper to someone who asks politely. Their email address is usually on the paper's first page or their university profile. A short note is enough: say who you are, which paper you'd like and why you're interested. Many authors also post copies on their own websites.

Once you have the paper

You don't need to read a research paper from start to finish. A practical order:

1. Abstract: the summary, including the design and main result.
2. Methods: who took part, how many, how they were recruited, what was measured. This is where you'll find most of the answers for the study checklist.
3. Results tables: look for the size of effects, not only significance stars.
4. Discussion and limitations: authors usually name the weaknesses of their own study here, often more frankly than any news story.
5. Funding and conflicts of interest: usually at the end.

If the statistics get dense, skip them and read the limitations section. It's often the most useful part for a non-specialist.

Check you've got the right version

Papers are sometimes corrected or retracted. On the journal's article page or in PubMed, look for notices of correction, an "expression of concern" or retraction. Retraction notices are linked from the original article in most databases.

With the paper open, the last step is comparing it with what the news said. That's the subject of the final guide, reading a news story about a study.
