Ovid MEDLINE Subject Limits
The online version of Ovid's MEDLINE now includes new limits based closely on PubMed's subject subsets. The addition of these subsets allows users to easily restrict a broad search to their specific area of interest:
History of Medicine
Space Life Sciences
Please be advised that Ovid has duplicated the PubMed subject subset searches as closely as possible; however, there can be differences in the number of records retrieved between the Ovid and PubMed subject subset searches.
