Lancho-Barrantes BS, Guerrero-Bote VP, de Moya-Anegon F. Citation increments between collaborating countries. Scientometrics 2013;94(3):817-831
International collaboration enhances citation impact. Collaborating with a country increments the citations received from it. The authors observed a certain tendency for these increments to be lower in countries with greater impacts, and differences in the behaviour of the countries between the various scientific disciplines, with the effects being greatest in Social Sciences, followed by Engineering.
