Author & Journal Self-citation and Impact Factor in Open Access Journals Indexed in DOAJ and ISI in Engineering Sciences During 2004-2005

The aim of this research is to survey relationship between (author and journal) self-citation and impact factor in open access journals indexed in DOAJ and ISI in engineering sciences during 2004 to 2005. Several indicators were studied: both 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 effect of number of journal self-citation on journal performance. For study, analysis data SPSS statistical software was used. The result showed that rate of author self-citation in Engineering sciences was 30% and in Sciences was 36%. The rate of Journal self-citation in engineering sciences was 25/3%. There was significant differences between the number of author and journal self-citation and the impact factor (P<0.01). After self-citation removal, in two said subjects, ranking change observed. In Engineering sciences 58% were positive, 19% negative and 23% without changing.
