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.
