Análisis de cobertura de referencia entre OpenAlex y Web of Science en artículos en coautoría Argentina-España (2013-2023)

This article analyzes the evolution of co-authorship between Spain and Argentina based on an analysis of 47,354 multidisciplinary scientific articles published between 2013 and 2023. Taking into account the different publication practices and circulation of knowledge between both countries, and the growth in their open access publications, two commercial indexing bases –Scopus and Web of Science– are compared with OpenAlex, which aspires to position itself as a more inclusive reference for bibliographic searches. The study shows that OpenAlex includes 27.9% more records than Web of Science and 29.3% more than Scopus; in addition to a greater presence of articles from social sciences and humanities compared to the two commercial databases, in which disciplines such as chemistry and immunology predominate. The analysis also highlights the role of universities and scientific organizations in the production and circulation of knowledge, based on an analysis of affiliations and publishing houses. The data suggest that the inclusion of OpenAlex allows for a more diverse view of scientific production and international collaborations, especially in traditionally underrepresented disciplines and geographic regions.
