June 26, 1997: The first search of PubMed by Vice President Al Gore at the US Capitol.[1]
MEDLINE® (Medical Literature Analysis and Retrieval System Online) is a database of predominantly biomedical bibliographic citations maintained by the U.S. National Library of Medicine (NLM).[2] Each citation includes bibliographic data, abstract if available, links to full text of the article and keywords. The keywords are indexed with the NLM's Medical Subject Headings (MeSH®).[3]
There are many third party interfaces to search MEDLINE such as OVID[4]. The National Library of Medicine's own search interface is PubMed (http://pubmed.gov).
Methods to improve searching MEDLINE
Filters (hedges)
MEDLINE filters are an optimal Boolean combination of search terms, both textword and MeSH terms, to search articles of particular types. For example, one filter is for identifying randomized controlled trials. Many MEDLINE filters have been developed by the Hedges team[5] supported by a grant from the National Library of Medicine.[6]
Methods to access MEDLINE
PubMed
PubMed (http://pubmed.gov) is the National Library of Medicine's own free Internet access to MEDLINE. PubMed has been freely available since its first search was performed by Vice President Al Gore during a press conference in the US Capitol on June 26, 1997.[1]
PubMed is hosted by the Entrez Search and Retrieval System of the National Center for Biotechnology Information[7] (NCBI) branch of the NLM[8] The hardware hosting Entrez has been described.[9]
