Türkçe Makalelerin Dergilere Dağılımı ve Bradford Yasası
Özet
Bibliometric findings obtained through the analyses of articles
published in journals are used to create scientific and technological
road maps and to develop collection management policies in
libraries. Yet such analytical studies reviewing the bibliometric
characteristics of Turkish articles are scarce. This paper tests if the
distribution of some 518,000 Turkish articles to journals conforms
to the Bradford Law. Data comes from the Bibliography of Articles
of the Republican Era 1923-1999 (BARE) that was recently
published on CD-ROM by the Turkish National Library. Although a
significant percentage of all articles in a given subject appeared in
a relatively few numbers of journals, the distribution of articles to
journals did not quite fit the Bradford Law. Eighty “core” journals
constituting only 3.2% of all journals contained one third of all
published articles while 182 journals contained half, and 358
journals contained two thirds of all articles. A library collection
containing the core Turkish journals will likely satisfy the significant
percentage of the information needs of users in scientific subjects.
Some 2,151 journals constituting 86% of all journals contained a
mere one third of all articles. The number of the most productive
core journals in each subject was higher than that predicted by the
Bradford Law. Articles in linguistics fitted the law best while articles
in technology, medicine, social and natural sciences and
mathematics fitted the least. Bibliographies with homogeneous
subjects seem to fit the classical Bradford Law better. Findings of
bibliometric studies should be used to measure the performance of
Turkish science and research, and to develop a science and technology “road map”. Core Turkish journals based on bibliometric findings should be acquired by libraries.
