A guide to the NLM databases

One of the more important questions for an author considering submitting an article for publication is whether a journal is indexed.

Being published in an indexed journal greatly enhances the discoverability of our research, so it is no small question! The databases of the National Library of Medicine (NLM) are highly regarded indexes of biomedical literature. What follows is a brief description of the NLM databases, followed by links to additional information.

MEDLINE® — This is a premier bibliographic database containing more than 29 million references to journal articles in life sciences. It is an extremely important resource for biomedical researchers worldwide, covering literature published from 1966 to present.

PubMed® — PubMed® is a free resource containing more than 34 million citations and abstracts of biomedical literature. PubMed facilitates searching across several NLM literature resources, including MEDLINE and PubMed Central®.

PubMed Central® — This is a free full-text archive of biomedical and life sciences journal literature. It is a repository for journal literature deposited by participating publishers as well as for author manuscripts.
