Use of scientific journals in Spanish universities: analysis of the relationship between citations and downloads in two university library consortia

We analyse the relationship between downloads of electronic journals included in four big deal bundles subscribed to by public university libraries affiliated to two library consortia in Spain (Castile and Leon and Galicia) and citations of the same journals by researchers at these universities. Download data on the big deals analysed (Emerald, ScienceDirect, Springer and Wiley) were obtained from COUNTER Journal Reports 1, and citation data were obtained from the bibliographic references given in articles indexed in Scopus between 2010 and 2017. The results show that only a low percentage of the subscribed journals was used in the scientific output of the universities' researchers, with values ranging from 15 to 50%, and that there was a strong correlation between the universities' volume of scientific production and the percentage of cited journals. We also found a strong correlation between downloads and citations, which was higher in the case of universities with a higher scientific output.
