Nowadays, the importance of Internet in the librarian world cannot be denied. Each time the number of services offered by libraries in the web is bigger, and literacy promoting activities are one of the aspects which is suffering this increase. We have tried to analyze the presence in the web of book clubs in Spanish public libraries, with the aim of knowing how they are developping, and trying to know if at the present a virtual service can substitute a presencial one. This can seem in contradiction with the own nature of this activity, where a book is just a pretext to get in contact with other people. Taking all this into account, we have located and studied the web pages of public libraies, and we have found diferent realities: very active web pages and others with just testimonial information.
