标题：Atıf Analizi: Hacettepe Üniversitesi Kütüphanecilik Bölümü Tezlerinde Atıf yapılan Kaynaklar / Citation Analysis: Sources Cited in Dissertations Completed at Hacettepe University Department of Librarianship
摘要：Bibliometrics deals with the quantitative analysis of some distinct
characteristics (i.e. authorship, subject, publication information, and
cited sources) of publications or documents. The process of scientific
communication in various fields can be investigated using bibliometric
data obtained in such studies. This paper analyzes the bibliometric
features of 100 master’s and doctoral dissertations completed at the
Department of Library Science of Hacettepe University between 1974
and 2002. An average dissertation was 171 pages long and contained
70 citations. Doctoral dissertations were twice as long as master’s
dissertations (275 pages as opposed to 142 pages). Similarly, the
average number of citations in a doctoral dissertation was 2.5 times
higher than that of a master’s dissertation. Monographs received half of
all citations (7019) while journals did 42%, dissertations and electronic
publications 3% each, and “other” documents such as unpublished
manuscripts 2%. The Türk Kütüphanecili¤i (the journal Turkish
Librarianship), Resm?Gazete (Official Gazette), College & Research
Libraries, Library Trends, Library Journal, Journal of the American
Society for Information Science and Unesco Bulletin for Libraries were
among the most frequently cited journals. Articles that appeared in the
top four and top 38 journals received 32% and 67% of all citations,
respectively. The distribution of citations to foreign journals fits the
Bradford’s Law of Scattering. The mean half-life of sources cited in
dissertations was 9 years. Sources cited in master’s dissertations were
younger than those of doctoral dissertations. The great majority of cited
resources in dissertations had single authorship. Findings obtained in
this study can be used to evaluate the library collections as well as to
develop a core journals list in librarianship.
