Health Science Database Ecosystem

There are two types of databases in the health sciences: subject databases and citation indexes.

Subject Databases for Health Sciences

PubMed vs OVID Medline

PubMed = Public Medline

MEDLINE is the largest component of PubMed (, the freely accessible online database of biomedical journal citations and abstracts created by the U.S. National Library of Medicine (NLM®). In addition to MEDLINE citations, PubMed also contains, among other items, in-process citations which provide a record for an article before it is indexed with MeSH and added to MEDLINE or converted to out-of-scope status. More information here

If you are searching Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE® Daily and Ovid MEDLINE® 1946-Present effectively, there is no reason to ALSO search PubMED. Ask your librarian for details. 

Key Citation Indexes

Health science research is often multidisciplinary. Below is a list of multidisciplinary databases to start you in the right path. You can also use these databases to conduct basic searches to 'scope' out a subject; quickly find seminal articles; and conduct bibliometrics research. We do not recommend searching these databases as part of a systematic review.
