The presence of Catalan culture will be inescapable at the IBF, which is to be held from 27 November to 5 December, not only thanks to the dense program of activities but also because of the 1,400-square-metre pavilion with a logo designed by Antoni Tàpies. The pavilion will be arranged round a series of modules which will be used to present not just the numerous aspects of Catalan culture – the Catalan language, the fine arts, the cuisine, architecture and design, not to mention science – but also the Catalan publishing industry, by means of a large bookshop, in fact the central part of the pavilion, which will display the books as well as offering them for sale. TV3 and Catalunya Ràdio will have their own studio within the pavilion. The Llull has put up a special Web site to cover its participation in the IBF, where day-by-day information about the events and participants in the Catalan culture program can be found. This resource can be accessed from the front page of the Institut’s main site from early November.

Apart from writers, academics and artists, the Catalan culture program will bring many representative of Catalan institutions to Guadalajara, notably the president of Catalonia, Pasqual Maragall, the Catalan ministers of culture, Caterina Mieras, trade and tourism, Josep Huguet, and higher education, research and the information society, Carles Solà, as well as the director general of language policy, Miquel Pueyo, and the chair of culture for Barcelona City Council, Ferran Mascarell. Also present will be the former Catalan president, Jordi Pujol, and the former speaker of the Catalan parliament, Joan Rigol. Also expected to attend is the present speaker of the Catalan parliament, Ernest Benach, accompanied by a delegation from each of the parliamentary groups. The Gremi d'Editors and the Associació d'Editors en Llengua Catalana will also be sending leading representatives to Mexico. In recent years the IBF has become a natural bridge between publishers in the American continent and those in the rest of the world. The Guadalajara Fair () is regarded as the most important such event in Latin America and the second in the world after Frankfurt. The statistics for last year’s fair show that there were 443,917 visitors, 1,498 publishers were represented, official bodies and companies from 38 countries took part and 14,416 members of the industry were accredited. Last year the IBF chose Catalan Culture as guest of honor for 2004 after assessing a proposal put forward by the Institut Ramon Llull, which it considered to be "very solid from the point of view both of publishing and of culture".
