Ovid Nursing Subject Thesaurus

ONST takes the familiar terminology of Medical Subject Headings (MeSH) as a starting point. While the thesaurus is MeSH-compatible, many inverted MeSH headings, (e.g. Education, Continuing) have been flipped to direct order (e.g., Continuing Education). This order maps more closely to natural-language forms, thereby making the selection of terms more intuitive for the end-user.
