PubMed is a free search engine offered by the United States National Library of Medicine as part of the Entrez information retrieval system. The inclusion of an article in PubMed does not endorse that article's contents. The PubMed service allows searching the MEDLINE database. MEDLINE covers over 4,800 journals published in the United States and more than 70 other countries primarily from 1966 to the present. In addition to MEDLINE, PubMed also offers access to:
Many PubMed citations contain links to full text articles which are freely available, often on the PubMed Central digital library.
PubMed is one of a number of search engines through which it is possible to search the MEDLINE database; the National Library of Medicine leases the MEDLINE information to a number of private vendors such as Ovid and SilverPlatter. PubMed has been available free on the Internet since the mid-1990s.
Because MEDLINE is the core component of PubMed, an understanding of MEDLINE is essential for effective searching in PubMed.
