RESTREPO ARANGO, Cristina y URBIZAGASTEGUI ALVARADO, Rubén. Authors' productivity of colombian library and information science. Ci. Inf. [online]. 2010, vol.39, n.3, pp.09-22. ISSN 0100-1965. http://dx.doi.org/10.1590/S0100-19652010000300001.
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.
