Legal Deposit
Office that receives editorial and audiovisual productions. Its main function is to collect and preserve all production on any support and enable access to the same. The items that are provided to the Legal Deposit of Catalonia can be consulted by users of three centres: the Library of Catalonia, the provincial public libraries of Barcelona, Girona, Lleida and Tarragona, and the National Library of Spain.

Methodological aspects

Data on publishing production is taken from different sources (INE, the Generalitat de Catalunya's Ministry of Culture data from the Spanish ISBN Agency, and the Library of Catalonia, with data on legal deposits). The divergence of the data is the result of each source relating to different phases of the publishing process. So, while the ISBN registration is made before publication and is in the name of the publisher, the legal deposit is made at the time of printing and is in the name of the printer.

The statistics reflect all documents presented to the Legal Deposit offices of Library of Catalonia over the year, regardless of the year of the legal deposit and therefore the year of publication.
