PubMed, the online version of MEDLINE (MEDlars onLINE), is
produced by the National Library of Medicine (NLM) at the US National
Institute for Health. The bibliographic database covers the fields of
medicine, nursing, dentistry, veterinary medicine, the health care
system, and the preclinical sciences. It contains bibliographic
citations (e.g., author, title, and journal reference) and author
abstracts from over 3,900 biomedical journals published in the United
States and 70 foreign countries. The process of selecting journals
for inclusion is described in the Fact Sheet, Journal Selection for
Index Medicus/MEDLINE contains over 19 million records dating back to
1966. Medline has worldwide coverage, but 88% of the citations in
current MEDLINE are for English language sources and 76% have English
abstracts. Citations for MEDLINE are created by the National Library
of Medicine, International MEDLARS partners, and cooperating
professional organizations. The database is updated monthly.
Note: when searching in PubMed you may truncate or shorten a word or phrases using a * (star or asterisk). For example, instead of using the word absorption you may instead use a * and the database will pick up the words absorption, absorbing, absorbed, and other variation of the word.
