Abstract :
Citation is one of the important elements in the scientific works and it has significant role in the production and publication of information. Part of the citation behavior is self-citation. Authors by citing their works can change citations and amount of impact factor. The aim of this research is to examine relationship between author and journal self-citation and impact factor in open access journals indexed in DOAJ and ISI in Science during 2004 to 2005. In this study several indicators were studied, i.e. the rate of author self-citation, and journal self-citation, relationship between author self-citation and impact factor, relationship between journal self-citation and impact factor, and the effect of number of journal self-citation on journal performance. Analytical research has been applied as the research method and in this regard technique "citation analysis" was employed. The results showed that the rate of author self-citation in 8 titles was 36% and the rate of journal self-citation in 54 titles was 26/1%. There were also significant differences between the number of author, journal self-citation and the impact factor (P<0.01) in the two subject disciplines.After discarding self-citation, in the field Science, ranking change was observed: 44% were positive, 30% negative and 26% static.
