Citation Analysis of the Croatian Medical Journal: the First 15 Years
Nataša Kovačić
Sažetak
The Croatian Medical Journal (CMJ) is a bimonthly scientific journal,
that publishes mostly original articles. It is indexed in the Index Medicus/
MEDLINE, Current Contents/Clinical Medicine, and the Science
Citation Index Expanded. Since the CMJ’s 15th anniversary in 2007,
our aim has been to assess the importance of the Journal through its
impact factor (IF) and immediacy index, with a particular focus placed
on the proportion of self-citations. According the Web of Knowledge
database, the current official IF for the CMJ is 0.825, ranking it 62nd
out of 103 journals within the Thomson Scientific category “Medicine
– General and Internal.” The exclusion of self-citations resulted in a
small decrease in the journal’s rank – to 66th place. According to the
Web of Science database, the predicted CMJ IF in 2007 is between
1.024 and 1.125, showing a clear increase. The immediacy index of the
CMJ is continuously low, with a high contribution of self-citations,
implying that articles published in the CMJ require more time to be
cited, and that their topics are of particular interest to the journal’s
readers and contributors. Self-citations contributed significantly to the
IF in the first few years after the journal was established. The proportion
of independent citations progressively increased, and of all the
citations included in the IF in 2007, almost 70% were fully independent.
Some of these citations were from articles published in journals
with IF higher than 5. Taken together, our data suggest that the CMJ
has significantly improved its citation ratings during the last 15 years,
confirming that a quality-oriented editorial policy in a small peripheral
journal may result in a truly increased international visibility.
