Abstract

State of the art review of the criteria used to judge and evaluate the quality of databases, including: content, ease of use, accessibility, customer support, documentation, and value to cost ratio. Concludes that the principle factor governing quality is content, defined by the scope and the coverage of the database and its currency, accuracy, consistency and completeness. Scope is determined by its composition and coverage, including time period, number of periodicals and other primary sources, number of articles and geographic and language distribution. Currency is measured by the time lag between publication of the primary source and availability of the corresponding records in the database. Accuracy is governed by the extent to which the records are free from errors of all types. Consistency depends on the extent to which records within the database follow the same rules. Completeness is measured by the consistency with which applicable data elements are assigned to all the records in the database. Reviews the major contributions to the literature in the field and summarizes the background of milestone studies
