PubMed is a key database for finding journal citations for biomedical literature. Currently, there are over 29 million citations in the database.
PubMed covers journals indexed by MEDLINE as well as non-MEDLINE journals. The National Library of Medicine (NLM) selects journals included in MEDLINE and indexes each with a MeSH subject heading, a controlled vocabulary. MeSH provides a hierarchy of organized terms for searching and understanding the topics in each journal.
