Abstract

Purpose - The purpose of this paper is to study the author self-citation behavior in four disciplines: electronic engineering, general and internal medicine, organic chemistry and plant sciences. Design/methodology/approach - By using SCI and random stratified method 1,000 articles were analysed as a sample in the four disciplines during 2004-2006. Findings - It was found that about 60 per cent of the articles in the four disciplines' literature contained at least one self-citation. Four disciplines all showed skewed distributions of articles citation rates, either self-citation or other citations. Organic chemistry articles had the highest self-citations than the other disciplines. Share of self-citation decreases with growing time window. The expected self-citation rate increased with growing number of citation, co-authorship and author productivity. Originality/value - The outcomes of this study suggest that self-citation indicators should be used as supplementary indicators in evaluative bibliometrics.
