This report describes a survey of 2,366 randomly selected U.S. academic, public, special, and school libraries which examined the usage and impact of the Cataloging in Publication (CIP) program on three areas of library operations: acquisitions, cataloging, and public services. Utlization of CIP data by a separate group of large U.S. libraries is also reviewed. Following discussion of the study's scope, objectives, background, and methodology, a summary of 25 findings and 9 recommendations for enhancing the CIP program is presented. It is recorded that a majority of all libraries responding to the survey use CIP data for one or more purposes, and that the majority of respondents express a favorable or very favorable opinion of the CIP program. In addition, high use of CIP for cataloging purposes, medium use for acquisition activities, and low use for public services are reported. A total of 61 tables throughout the main body of the report present statistical answers to 37 questions on the usage, benefits, and problems of the CIP program and possible changes and/or improvements to it. Appendices comprise a brief description of CIP, a list of members of the CIP Advisory Group, and a sample questionnaire and survey cover letter. (ESR)
