AbstractThis study evaluates Ph.D. theses in physics, submitted to the North Bengal University Darjeeling, West Bengal during 1987 to 2007. This study aims to determine the year wise distribution of theses, the guideship pattern, to determine the most productive guides and average number of citations per theses. The study also investigate the citation distribution 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, and to view the chronological distribution of cited literature, which will show the time during which literature in the particular subjects remains active. The study presents the trends in authorship pattern and collaborative research in physics. Journals and Books/monographs were the two formats that were most frequently cited in Physics (81.76% and 8.34%). The ratio between single and multi-authored papers is approximately 1:3. The degree of collaboration in physics is 0.774. The study indicates that maximum references were used during the year of 1980-1989. Journals published in India, USA, United Kingdom and the Netherlands are popular among the University science researchers. The most frequently cited journal titles were The Physics Letter, Physics Review A, Mol. Cryst. Liq. Crystal.
