    Abstract
    Analyzes user requests resulting in zero hits for author searches in online catalogs. Discusses the need for bibliographic records relating to a name to brought together under one form of the name and the need for cross references from variant forms of the name. Presents data which prove that linked bibliographic/authority files and the availability of see references online in the OPAC reduce the number of times that author searches produce zero hits

    Abstract
    Investigates the reasons for one category of zeor hit author searches - that of plausible but unverifiable names - encountered by end users of the NOTIS OPAC at the University of Illinois at Chicago. The names were not found in the national bibliographic utility (OCLC), the local database (LUIS), the local card catalogue, or large online files of journal articles (Wilson indexes). Concludes that, while the problem of user queries resulting in no retrievals cannot be entirely remedied, a number of things can be done to minimize the problem, including: putting in palce an international system to exchange authority data for names; simplification of cataloguing riles; a retrieval system that allows natural language best match retrieval, ranked output, relevance feedback, and other post Boolean techniques; expanded use of keyword searching; and user education

    Abstract
    Describes an attempt, by Illinois University at Chicago (IUC) Library to respond to user needs as they are revealed in transaction logs of OPAC use. Illustrates success in improving access to catalogue records through a reengineering process. Outlines the IUC Library Reengineering Project, the administrative structure to study transaction logs, and the resultant managerial decisions. Notes the changes made to sreen display and to the OPAC. Focusing on customer satisfaction, IUC catalogue librarians joined forces with colleagues to identify Usrs' unmet needs and preferences through transaction log analysis. In order to minimize mismatches between users' expectations and services actually provided, IUC catalogue librarians studied logs and adjusted the OPAC. Descrinbes the specific efforts to increase access to the library's collections and the steps taken to enhance and customize bibliographic and authority records. Concludes that transition log analysis has enabled IUC to alter the form and content of its OPAC to fit the changing needs of diverse and widely disoersed users
