The PubMed Dietary Supplement Subset (PMDSS) is a joint project between the National Institutes of Health (NIH) National Library of Medicine (NLM) and the NIH Office of Dietary Supplements (ODS). PMDSS is designed to help people search for academic journal articles related to dietary supplement literature. The subset was created using a search strategy that includes terms provided by the Office of Dietary Supplements , and selected journals indexed for PubMed that include significant dietary supplement related content. It succeeds the International Bibliographic Information on Dietary Supplements (IBIDS) database, 1999-2010, which was a collaboration between the Office of Dietary Supplements and the U.S. Department of Agriculture's National Agricultural Library.
