摘要

A study of the Dialog database versions of ISA and its close competitors, LISA and Library Literature & Information Science, characterized the coverage, overlap among the databases, and types of documents indexed in 1999 and early 2000. In 20 LIS subject searches, Library Literature retrieved the most records in 16 of the searches, Lisa had the most in three, and they tied in one. ISA had the least records for all topics, a natural result of adding significantly fewer records overall. For any subject, the maximum overlap of titles among the three databases was only 21%, indicating the need to search more than one database for comprehensive results.
