 What is PubMed?


PubMed provides free access to the National Library of Medicine (NLM)'s database of indexed citations, MEDLINE.  Along with MEDLINE, PubMed also provides access to PubMedCentral, NCBI Bookshelf, OLDMEDLINE (Pre-1966 citations), and In-Process Citations.

It contains over 30 million citations from medical, nursing, dental, veterinary, health care, and preclinical sciences journal articles.  These citations come from over 5,600 scholarly journals published around the world.  These journals are in numerous languages and date back as far as 1946 with new citations added daily.  Many of the citations link to Free Full Text articles.  However, if you want an article that does not have a Free Full Text link, please submit an Interlibrary Loan Request.

PubMed was developed by the National Center for Biotechnology (NCBI) at the National Library of Medicine (NLM).
