Introduction

PubMed, a service of the National Library of Medicine, provides access to millions of citations from MEDLINE and additional life science journals. PubMed includes links to many sites providing full text articles and other related resources.

Ovid MEDLINE ® covers the international journal literature on biomedicine, including the allied health fields and the biological and physical sciences, humanities, and information science as they relate to medicine and health care.

PubMed and MEDLINE are key databases for the following subject areas:
