PubMed® Subject Subset Strategies Updated for 2009
PubMed subject subset strategies are reviewed at least once a year to see if modifications are necessary. Modifications may include revisions due to changes in MeSH® vocabulary, adding or deleting terms, and changing parts of a strategy to try to optimize retrieval. The following subset strategies were recently revised: Bioethics, Cancer, Complementary Medicine, Space Life Sciences, and Toxicology.
