Authors' productivity of colombian library and information science

Abstract

The scientific productivity of the authors who have published papers in four journals of library and information science from Colombia since 1978 to 2009, was analyzed. A total of 555 authors were found; 422 (76%) of them published a single article and 78 (24%) published 2 or more articles. Eleven authors were considered as the most productive with 21 and 7 articles respectively. The data was analyzed with the generalized inverse power, inverse generalized Gauss Poisson, and Poisson lognormal models by the maximum likelihood method. The statistical chi-square and K-S tests showed that the three models fit the observed data.
