Looseleaf publications are truly a unique type of library material, partaking simultaneously of the nature of serials and monographs. Therefors, two disparate methods of cataloging looseleaf publications coexist today. But the decision to catalog looseleaf publications as serials as monographs affects the acquisition, budget allocation, receipt, record maintenance, and user access. In view of these aspects, this study analyzed the sources of information and seven areas of description (title and statement of responsibility ; edition ; publication, distribution, etc. ; physical description; series ; note ; standard number and terms of availability) of CRDLP2 as the exclusive cataloging rules of looseleaf publications. The results of the analysis were summarized in chapter 4 in detail. Finally, it is desirable that looseleaf publications for updationg are cataloged as monographs since the bibliographic description applied to looseleaf publications follows so colosely that of monographs. And, the cataloger must pay partioular attention to describe the physical description area because of numerous changes of the bibliographic records accompanied by frequent revisions or updates of the publications.
