CUC 2004 E4 Jadranka Stojanovski, Đurđica Težak - Self-citations and impact factors of Croatian jour
Twelve Croatian periodicals as referred in the Journal Citation Reports (JCR) published by Institute for Scientific Information (ISI) were analyzed with the emphasis on self-citations. Although it is expected from author to mention his/her earlier research in the new articles, the extent of self-citation should be reasonable. Especially referring to the previous work published in the same journal could potentially influence impact factor of the journal. In order to determinate the amount of self-citations among all other citations journal's self-citing rate as the percentage of citations given by the journal to itself and a journal's self-cited rate as percentage of citations received by the journal from itself was calculated for each journal.
