A study on journal self-citations and intra-citing within the subject category of multidisciplinary sciences

For academic research outcomes, there is an increasing emphasis on the bibliometric scorings like the journal impact factor and citations when the assessment of the scientific merits of research or researchers is required. Currently, no known study has been conducted to explore the bibliographical trends of the subject category of multidisciplinary sciences as indexed by the annual Journal Citation Reports of the Thomson Scientific. The effect of journal self-citations and intra-citing within a discipline to the bibliometric data computation can be confounding. In this study, six journals were selected from the multidisciplinary sciences subject category where the trend of self-citations and intra-citing were analysed. These journals were chosen as they published more than 450 citable articles in the year 2007 and had available bibliometric data for a 10-year period. The results showed that self-citations rose as much as +23.98% while intra-citing declined up to -5.80% over the observed period. The retrospective impacts and influences of these observations were also discussed in this study.
