Greco A, Bornmann L, Marx W. Bibliometric analysis of scientific development in countries of the Union of South American Nations (Unasur). [article in Spanish] El profesional de la información 2012;21(6):607-612
Using advanced bibliometric methods, this paper investigated for the first time the development of science and technology in the Unasur region in comparison to other countries worldwide in terms of bibliometric data. The publication output results revealed an increase in the scientific and technological activities in most of the Unasur countries (especially Brazil). However, compared to the rest of the world, the trend of citation impact is less favourable for all Unasur countries.
