"Polska Bibliografia Bibliologiczna" jako źródło danych do badań bibliometrycznych, na przykładzie problematyki bibliotek toruńskich

Despite changes in methods of transferring information, printed publications are still an important means of spreading knowledge and have an established position among academics. They also constitute an essential element which evaluates academic achievements of academics and researchers. It is more and more frequent that bibliographical descriptions or some of their parts are employed in the process of such evaluations besides various quality meters (impact factor, Hirsch’s and Egghe’s indexes, the scoring of the Ministry of Science and Higher Education). On this basis the relations between documents are established and parameters characterizing their collections and features are defined. The article is an attempt to show this type of relationship. It presents the results of the examination of the collection of documents dedicated to the libraries in Torun, and registered in the “Polish Bibliological Bibliography” in the years 1995-2011. The research material comprises the collection of 264 bibliographical works such as books and their versions before the final revision, periodicals, articles from the press and fragments of joint publications. The author analyses the quantity and content of the material collected, paying special attention to both the rapid growth in the number of publications, the variety of publishing forms, the thematic range of published works, and the specificity of the “Polish Bibliological Bibliography“ as a source of data to bibliometrical research
