The Network of Municipal Libraries provides access to more than eight million documents (books, DVDs, CDs, magazines and newspapers), which you can find on Aladí, the Network's collective catalog. 

Loans are free of charge and enable users to take home up to 30 documents (21 in the case of the bookmobiles) for 30 days. You only need a library card  which is valid at all public libraries in Catalonia and also enables you to enjoy discounts on cultural events

You can also download e-books on the site eBiblio CatalunyaMore information about the service 'E-books Loan Service'.
