Se encontraron 936 documentos producidos por 1 123 autores diferentes. Estos autores utilizaron 16 idiomas para comunicar los resultados de sus investigaciones; el inglés fue el idioma dominante, seguido del chino, español y portugués. Se identificó también a 15 autores como los más productivos, quienes publican sus investigaciones en inglés, en la forma de artículos en revistas académicas, y las presentan en congresos del área. Esta literatura crece de forma exponencial (R2 = 0.974), a una tasa de 5.4 % al año y duplica su tamaño cada 13.2 años.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[This paper analyzes the literature produced on Bradford' Law from 1934 to June 2012. The study compiled 936 documents produced by 1,123 authors, working in sixteen languages to communicate the results of their research, with English the leading language, followed by Chinese, Spanish and Portuguese. The study reveals the fifteen most productive authors, all of which work in English in both academic journals and conference settings. This literature is growing exponentially (R2 = 0.974), at a rate of 5.4% per year and doubling in size every 13.2 years.]]></p></abstract>
