    Abstract
    Reports on a Centre for Information Quality Management (CIQM) BLRRD funded project which investigated the quality of databases in general use in the UK. Gives a literature review of quality in library and information services. Reports the results of a CIQM questionnaire survey on the quality problems of databases and their affect on users. Carries out databases evaluations of: INSPEC on ESA-IRS, INSPEC on KR Data-Star, INSPEC on UMI CD-ROM, BNB on CD-ROM, and Information Science Abstracts Plus CD-ROM. Sets out a methodology for evaluation of bibliographic databases
