Semiperiodo de la literature científica en biblioteconomía y documentación y la influencia de los aspectos temáticos

Abstract

Following the formula developed by Burton and Kebler,this paper presents a calculation of the half-life of bibliographical references appearing in twenty-eight English- and Spanish-language Library and Information Science journals in the year 2006. An analysis ofthe relationship of this phenomenon to content is carriedout in order to identify the nuclear topic areas thatin turn determine this half-life. Moreover, the paperprovides an assessment of those subject areas for eachof the journals studied that tend to lengthen or shortenthe half-life of a given bibliographic reference. Assuch, the bibliographic half-life may be considered anindicator of the thematic inclination of a given journal.
