Abstract: This study evaluates Ph.D. theses in sciences, submitted to the University of Malaya, housed in the Perpustakaan Peringatan Za'ba during 1986 to 1995. The subjects included in this study according to the Library of Congress Classification are : QA Mathematics, QC Physics, QD Chemistry, QK Botany, QL Zoology and QR Microbiology. The citation distributions in terms of bibliographic formats and source of information have been studied. This study aims to determine the citation distribution in terms of bibliographic formats to show which format is cited most in each subject of science, to identify the characteristics of the cited references in terms of format, source of information, age, and to view the chronological distribution of cited literature, which will show the time during which literature in the particular subjects remains active. The information about these theses has been obtained through searching the OPAC terminals of the University Malays Library, using the terms Ph.D., thesis, and Malaya. Out of the 663 records found, only 41 theses belonged to Science from the year 1986 to 1995 were used in the data collection. Their bibliographic information was keyed into Microsoft Access. The collection of the citations data in this research was carried out using Re- prospective Conversion Methods and a total of 8,736 citations were collected. The purpose of this compilation was to count the total number of citations for each subject in the field of science. Journals and monographs were the two formats that were most frequently cited, 74.94% and 15.76% respectively. The average half-life period for the entire literature is found to be over 13 years. The two most frequently cited journal titles were: Journal of Organometallic Chemistry and Journal of Chemical Society. List of core journals with the most frequently cited are recommended for acquisition in conjunction with the collection development policy for science.
