Title

Controlled vocabularies for MEDLARS databases

Abstract

For many years, searching medical and health-related topics has caused thousands of searchers to consult the well-known Medical Subject Headings (MeSH) controlled vocabulary. This plan works well for searching MEDLINE, but what about the MEDLARS databases such as TOXLIT, BIOETHICSLINE and POPLINE? Several printed vocabularies are available for searchers who wish to benefit from the consistency afforded by consulting established term lists. Occasionally, use of keywords from vocabularies other than MeSH is recommended even when information in the database is also indexed to MeSH. Search techniques available for use with several of the controlled vocabularies which are discussed vary, but built-in consistency of term use is a continuing theme from one controlled vocabulary to another
