PubMed® Subject Subset Strategies Updated for 2007

NLM announced that the following subject subset strategies have been recently revised: AIDS, Bioethics, Cancer, Complementary Medicine, Systematic Reviews, and Toxicology.

All 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 History of Medicine subset was revised in October 2006.
