@article{aksnes2003macro, abstract = {This study investigates the role of self-citation in the scientific production of Norway (1981-1996). More than 45,000 publications have been analysed. Using a three-year citation window we find that 36% of all citations represent author self-citations. However, this percentage is decreasing when citations are traced for longer periods. We find the highest share of self-citation among the least cited papers. There is a strong positive correlation between the number of self-citations and the number of authors of the publications. Still, only a minor part of the overall increase in citation rates that can be found for multi-authored papers is due to self-citations. Also, the share of self-citation shows significant variations among different scientific disciplines. The results are relevant for the discussion concerning use of citation indicators in research assessments.}, author = {Aksnes, Dag W.}, doi = {10.1023/A:1021919228368}, interhash = {d929a33337bbbcc3b3bc1ebc2d1fe3d3}, intrahash = {b76d63d366bb3ca267df1c4f92979b69}, issn = {0138-9130}, journal = {Scientometrics}, language = {English}, number = 2, pages = {235-246}, publisher = {Kluwer Academic Publishers}, title = {A macro study of self-citation}, url = {http://dx.doi.org/10.1023/A%3A1021919228368}, volume = 56, year = 2003 }
