To try to answer that question and show the bookish dimension of the city, we visited the palacio del Baró de Quadras (headquarters of the Ramon Llull Institute), the Mercat de Sant Antoni, the Library of the Water Deposit and the Gabriel García Márquez, the Supercomputing Center and the bookstores +Bernat, Nollegiu, La Calders, Ona, La Central, La Petita and Finestres. With interviews with the booksellers Montse Serrano and Xavier Vidal, the writer Enrique Vila-Matas, the editor Jorge Herralde and the children's illustrator Rocio Bonilla
