In order to find the resources that users need, the Spanish National Research Council (CSIC) Libraries Network provides several catalogues:
When searching all combined collections you are searching simultaneously the Bibliographic Catalogue (including e-books and e-journals titles), the Archives Catalogue as well as documents included in Digital.CSIC’s Institutional Repository.
This catalogue provides information about the collections that are within the CSIC Libraries Network and some of its associated centres.
This option allows users to access e-books collection, digital documents and e-journals available to CSIC libraries. E-journals and e-books records include links to full text. Most of them can be accessed only by CSIC users. A selection of free e-books and e-journals is also included.
