D’EP Institut has collaborated with the Department of Culture of the Generalitat of Catalonia in the development of the Library Statistics 2020, which is part of the National Statistical Plan and aims to obtain quality indicators in the library sector.

To carry out this study, data from non-public libraries have been collected through an online questionnaire, and simultaneously, the database of information regarding public libraries has been input. After conducting the cleaning and validation of all data, the obtained results have been disseminated through statistical reports prepared in different formats.
