Title
Analysis of retrieval performance in four cross-disciplinary databases : Article1st, Faxon Finder, UnCover, and a locally mounted database

Abstract
As an increasing number of cross disciplinary databases become accessible over the Internet, librarians are presented with the dilemma of which to choose to support user research. Several factors, such as cost, retrospective coverage, and document delivery, are usually considered in making a decision. However, one key factor: citation retrieval performance is often overlooked because comparative data has been unavailable. A study of 4 cross disciplinary databases was undertaken to provide those data. The databases consulted were: Article1st; UnCover; Faxon Finder; and GENL (a database comprised of 6 locally mounted Wilson databases: Readers' Guide to Periodical Literature; Business Periodicals Index; Humanities Index; Social Sciences Index; General Science Index; and Index to Legal Periodical Literature). In addition to citation frequency distribution, 2 other variables were examined; percentage of unique periodicals cited per search and relevance of citations to stated search topic. Presents an analysis of the data with its implications for database selection
