Medline/PubMed
PubMed is a free database accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
From 1971 to 1997, MEDLINE online access to the MEDLARS computerized database had been primarily through institutional facilities like medical libraries. PubMed, first released in January 1996, ushered in the era of private, free, and home-computerized MEDLINE searching.[1] The PubMed system was offered free to the public in June, 1997.
In addition to MEDLINE, PubMed provides access to:
- older references from the print version of Index Medicus back to 1951 and earlier;
- references to some journals before they were indexed in Index Medicus and MEDLINE, for instance Science, BMJ, and Annals of Surgery;
- very recent entries to records for an article before it is indexed withMedical Subject Headings (MeSH) and added to MEDLINE; and
- a collection of books available full-text and other subsets of NLM records.[3]
- PMC citations
Many PubMed records contain links to full text articles, some of which are freely available, often in PubMed Central[4] and local mirrors such as Europe PubMed Central.[5]
Information about the journals indexed in PubMed is found in the NLM Catalog.[6]
As of October 3rd, 2013, PubMed has over 23 million records going back to 1966, selectively to the year 1865, and very selectively to 1809; about 500,000 new records are added each year. As of the same date, 13.1 million of PubMed's records are listed with their abstracts, and 14.2 million articles have links to full-text (of which 3.8 million articles are available full-text for free for any user). To see the current size of the database type "1800:2100[dp]" or "all[sb]" into the PubMed search window.[7] (PubMed)
