From Wikipedia, the free encyclopedia

PubMed is provided by the United States National Library of Medicine.

PubMed is a free search engine offering access to the MEDLINE database of citations and abstracts of biomedical research articles. The core subject is medicine, and PubMed covers fields related to medicine, such as nursing and other allied health disciplines. It also provides very full coverage of the related biomedical sciences, such as biochemistry and cell biology. It is offered by the United States National Library of Medicine as part of the Entrez information retrieval system. As with other indexes, the inclusion of an article in PubMed does not endorse that article's contents. 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

• OLDMEDLINE for pre-1966 citations.
• Citations to all articles, even those that are out-of-scope (e.g., covering plate tectonics or astrophysics) from certain MEDLINE journals, primarily the most important general science and chemistry journals, from which the life sciences articles are indexed for MEDLINE.
• In-process citations which provide a record for an article before it is indexed with MeSH and added to MEDLINE or converted to out-of-scope status.
• Citations that precede the date that a journal was selected for MEDLINE indexing (when supplied electronically by the publisher).
• Some life science journals that submit full text to PubMed Central and may not have been recommended for inclusion in MEDLINE although they have undergone a review by NLM, and some physics journals that were part of a prototype PubMed in the early to mid-1990's.[1]

Many PubMed citations contain links to full text articles which are freely available, often in 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 also leases the MEDLINE information to a number of private vendors such as Ovid and SilverPlatter--as well as many other vendors. PubMed has been available free on the Internet since the mid-1990s.

For optimal searching in PubMed, it is necessary to have a thorough understanding of its core component, MEDLINE, and especially of the MeSH controlled vocabulary used to index MEDLINE articles.

Information about the journals indexed in PubMed is found in its Journals Database, searchable by subject or journal title, Title Abbreviation, the NLM ID (NLM's unique journal identifier), the ISO abbreviation, and both the print and electronic International Standard Serial Numbers (pISSN and eISSN). The database includes all journals in all Entrez databases.
