PubMed is a free database including primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
The terms "free", "subscription", and "free & subscription" will refer to the availability of the website as well as the journal articles used.
