How to Find Free Full-Text Medical Research Articles

You can find many medical articles free and legally by using the free full-text filter in PubMed, searching PubMed Central, checking open-access journals and repositories, looking for author manuscripts and preprints, and using library or interlibrary-loan services.

Reliable sources

• PubMed "free full text" filter: limits results to records with free full text links.
• PubMed Central (PMC): NLM's free full-text archive of biomedical articles, including content from open-access journals and funder-mandated manuscripts.
• Open-access journals: directories such as DOAJ list vetted open-access journals.
• Preprint servers: such as medRxiv; preprints have not been peer reviewed, so cite them as such.
• Institutional and subject repositories: authors may deposit accepted manuscripts.
• Funder portals that host publicly funded research.
• Your library: subscription access, interlibrary loan, and librarians who can help.
• Email the author: authors are often happy to share a copy for personal use.

Steps

1. Search PubMed and apply the free full text filter.
2. If not available, search the title in PMC and a repository.
3. Check whether there is a preprint or accepted manuscript.
4. Ask your library or the corresponding author.

What to avoid

Avoid pirate sites, which break copyright law and may expose you to malware. Use only lawful channels.

Illustrative example

Invented for teaching. A student cannot access a paywalled article. A PubMed Central search finds the author's accepted manuscript, deposited under a funder policy. She cites the published version and notes in her reading list that she read the manuscript copy.

Common pitfalls

• Citing a preprint as if it were the final paper.
• Using unauthorised copies.

Key takeaways

• PubMed filters, PMC, repositories and your library cover most needs.
• Check the version (preprint, accepted manuscript or final).
