The National Library of Medicine's (NLM) MEDLINE database is the most important bibliographic database in the bio and related sciences. MEDLINE is freely accessible via the PubMed web interface, but NLM also licenses MEDLINE data to information service providers including EBSCOhost, ProQuest, Ovid, and Web of Science. The talk covers a longitudinal study of these five MEDLINE-based bibliographic database platforms. The goal of the study is to identify where and how these platforms differ when searched with semantically and logically equivalent search queries. The results have implications for literature searches, including systematic reviews.
