PubMed
PubMed is a free biomedical literature search website for citations, abstracts, MEDLINE records, MeSH terms, author searches, related articles, and links to full text when available.
What PubMed is
PubMed is a search website at pubmed.ncbi.nlm.nih.gov for biomedical and life sciences literature. It is operated by the National Center for Biotechnology Information (NCBI) at the U.S. National Library of Medicine (NLM), and it helps users find journal citations, abstracts, author records, subject terms, related articles, and links to full text when those links are available.
What a PubMed record shows
A PubMed record is not just a title in a search list. It can include authors, affiliations, journal details, publication date, abstract, PubMed ID, DOI, publication type, MeSH terms, grant support, conflict information when supplied by the article source, and links to related resources. The record is a map to the literature, not a substitute for reading the paper carefully.
MEDLINE and other sources
MEDLINE is the major curated bibliographic component inside PubMed, but PubMed is broader than MEDLINE alone. NLM describes MEDLINE content as searchable through PubMed, while PubMed also includes citations from other selected life science sources, online books, and records that may link to full text in PubMed Central or publisher websites.
Searching with terms and fields
PubMed supports simple keyword search, but its power comes from field tags, filters, author names, journal names, date ranges, article types, and Medical Subject Headings (MeSH). MeSH terms help group articles by biomedical concepts even when authors use different wording. Good searches often combine plain-language terms with controlled vocabulary and then refine by evidence type.
Reading results responsibly
A PubMed result can point to a randomized trial, review, case report, editorial, letter, animal study, lab experiment, guideline, or correction. Those article types carry different kinds of evidence. Readers should check the study design, sample size, population, funding, conflicts, statistical methods, limitations, and whether later articles confirm or challenge the result.
Links to full text
PubMed does not automatically mean a paper is free to read in full. Some records link to free full text through PubMed Central, an open access article, a publisher page, or an institutional library. Other records may show only citation and abstract information unless the reader has access through a subscription, purchase, author manuscript, or another legal copy.
Why researchers and clinicians use it
PubMed is common in medicine, public health, biology, pharmacy, nursing, dentistry, and adjacent fields because it gives a shared starting point for literature searches. It is especially useful for finding known papers, building search strategies, following citations by author or topic, checking publication details, and moving from one article to related work.
Why it matters
PubMed matters because health decisions, research reviews, clinical guidelines, and public debates often depend on finding the original biomedical literature. A public search website cannot judge evidence for the reader, but it makes the trail to the evidence easier to inspect: what was published, where it appeared, how it was indexed, and how it connects to the wider literature.
