PubMed
pubmed.ncbi.nlm.nih.gov
The National Library of Medicine's free database of over 35 million citations for biomedical literature, with full-text links where available.
Why it is useful
The authoritative starting point for any biomedical research — comprehensive, well-indexed, and free. Many results link directly to PubMed Central where the full text is freely available. For patients, journalists, and researchers trying to understand medical evidence, the MeSH term filtering and related article suggestions make navigating a dense field significantly easier.
