Solapamiento y singularidad de MEDLINE, WoS e IME para el análisis de la actividad científica de una región en Ciencias de la Salud

Abstract

The inclusion of a single affiliation address in MEDLINE bibliographic records is a well-known important limitation for the use of this database for bibliometric purposes. This paper provides quantitative data regarding the effects of this limitation on the quantity and impact of the scientific production of a Spanish region measured via MEDLINE. It is estimated that 1/3 of the papers produced by this region cannot be identified in this database because the region does not appear in the affiliation address. Moreover, the impact of the region tends to be undervalued since these collaborative papers are published in «bẽtter» journals and receive more citations than many other publications.
