How it works

The database is free for everyone, with no account needed. You can search by topic, author, journal, or MeSH term, filter by study type and date, and save your searches. It links to full text where available, and to related articles for every result.

PubMed is the default search tool for biomedical research. It will not help outside medicine and life sciences, and its interface is older than newer tools, but for a free, comprehensive search of the medical literature it is the authoritative choice.
