Abstract:
The purposes of this thesis were: to study the similarities and differences of the cataloguing data for Thai series currently practiced by the university libraries and the National Library in Thailand; to compare the research data with the Anglo-American Cataloguing Rules, second edition (AACR 2); and to present the cataloguing approaches for Thai series upon which most libraries agreed in order that the desirable co cataloguing policy for the university libraries can be formulated uniformly and effectively. Data were collected through a number of 12 questionnaires distributed to the Head Librarians of Thai Books Classification and Cataloguing Department in 12 libraries. The completed questionnaires were totally returned. The results of the research disclosed that 12 university libraries and the National Library have different cataloguing methods and follow different policies. Most libraries consult both Thai and English cataloguing rules. Apparently 9 volumes of cataloguing manuals are being used. Cataloguing policies for Thai series discovered from the research illustrated that a main card for each title and a series card are applied in the majority of libraries. Some libraries have series cards for all Thai series while some do not have. Most libraries print added cards for each book in a same series. Research findings also revealed that most of the libraries apply a personal auther as a main entry, a book little as a title area and a series title with a series number as a series area. Name of the libraries completely followed the AACR 2, but some libraries have considered the full AACR 2 implementation for Thai series. Recommendations:- 1. Catalogers of both university libraries and the National Library should actively collaborate in order to standardize as well as publish manuals for Thai series cataloguing rules in terms of unified main entries, title entries, series area and added entries. 2. A Combined series card should be produced. 3. Libraries should catalog a series area completely following the AACR 2 in preparation for future computer application, then searching Thai series data can be facilitated. 4. Library Schools should consider revising as well as redinecting cataloguing courses. Thai series cataloguing should be more emphasized. 5. Publishers, editors and authors of Thai series should regard the established standards for series printing in order that more qualitation volume can be produced.
