What is PubMed?

PubMed is a freely available database developed and maintaned by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine. It contains over 24 million citations for biomedical literature indexed in MEDLINE, life sciences journals, and electronic books. Entries from MEDLINE journals, which are chosen by a committee of experts, are abstracted and indexed with Medical Subject Headings (MeSH). 

PubMed and its search features are free for anyone to use. Himmelfarb Library also provides access to MEDLINE through Ovid, a subscription database. Click on the Search MEDLINE tab to find out more about how to use this interface.

PubMed Central (PMC)

PubMed Central is a free full-text archive within PubMed. It contains publications that have been submitted in compliance with the NIH Public Access Policy and the requirements of other funding agencies. PMC manuscripts are free for anyone to download.

Note that the version of a manuscript deposited in PMC may not be the same as the publisher's final edited version, or the Version of Record. In many cases, the PMC version is the author's manuscript, or the "post print" version.
