Fortalezas y debilidades de las principales bases de datos de información científica desde una perspectiva bibliométrica

e present papers studies the most relevant scientific information databases at regional and international level from theperspective of their characteristics and functionalities. e main objective is to identify the strengths and weaknesses of thissecondary sources through the analysis of their indexing capabilities, coverage, interoperability and scientific information searchand recovery for the bibliometric activity. On the basis of information observation and collection from each database website, twoad hoc design tables are developed in order to analyse and compare their performance according to a series of dimensions thatcover from formal aspects (origin, purpose, scope) to functional aspects (access, format, quality). Reflection on the contribution ofthese sources to the matrix construction that allow the development and calculation of indicators for scientific activity evaluationis made. A strong tendency of the systems towards the search and recovery service for bibliographic research, without added valuefor the reuse of data, is observed. It is concluded that most of the studied systems require hard work on the restructuring andenrichment of the records so that their data export services constitute true tools for bibliometric research.
