This study examines how CIP program of the Library of Congress distributes, provides an access to, and helps upgrade CIP data through bibliographic utilities. LC CIP program can be characterized by the participation of many U.S. mainstream publishers, a continuing increase in the number of CIP data assigned annually, and an effort to immediately upgrade the completeness and accuracy of CIP data in cooperation with bibliographic utilities. Cooperation between LC and bibliographic utilities in performing quality control is worth noting, when compared with the limitation of CIP program of the National Library of Korea. It is suggested that the National Library of Korea should provide complete and accurate bibliographic and authority records for other types of new and old library materials published in Korea as well as CIP data for new monographic materials.

The KERIS Union Catalog is the largest bibliographic database in Korea. It has over 5.7 million bibliographic records and at present 330 university libraries are participating in shared cataloging services. The database, however, includes various errors and a large number of duplicate data because separate databases from many university libraries were merged without proper quality control in a short period. This study intends to find error data types by analyzing dissertation bibliographic data. The results show that error data are mainly caused by input errors, and the mistakes in using MARC formats and cataloging rules.

In the recent cataloging environment, the function of authority data is becoming more important. In Korea, a pilot project for sharing and joint use of the national authority data has been promoted since 2019, and a plan to automatically construct retrospective authority data using national authorities is in progress. This study aims to (1) analyze the results of the pilot project for retrospective authority data jointly promoted by the National Library of Korea and KERIS in 2019, (2) explore methodological limitations and problems in the process, and (3) derive policy proposals for constructing authority data more efficiently. To this end, a university library participating in the pilot project was investigated as a case study. Based on it, the automatic generation rate and accuracy of authority data, and errors and omissions cases and causes were analyzed in detail. As a results of the study, it was found that the quality of union catalogs and bibliographic records had a great influence on automatically constructing authority data, and supplementary methods were needed to minimize these limitations.
