PubMed and Medline are both biomedical literature databases produced by the US National Library of Medicine. PubMed contains over 22 million citations including Medline citations as well as other sources. Medline contains approximately 18 million citations from over 5,000 journals. The main differences are that PubMed has a broader scope, more search features, and allows access to some full text articles, while Medline provides more controlled vocabulary searching and limits. Both are useful research tools.
