Libros Mutantes is a Spain-based independent project focused on the relation between publishing and Visual Arts. Throughout the year they organise different events in order to bring this creative universe closer to the public. The main event in their calendar is Libros Mutantes Madrid Art Book Fair, held at La Casa Encendida.

Since 2010, this Art Book Fair gathers a wide selection of national and international art books, independent publications and zines, and attracts a wide audience.

This makes Libros Mutantes the largest and most comprehensive Spain-based project aimed at researching and spreading the creations of independent publishers.
