The creation of co-operative networks for sharing information has been one of the most significant advances of recent decades in Cuba; they have been set up in various areas of knowledge in order to solve the problems caused by the increasing accumulation of data, images, ideas, information and objects. The difficulties faced daily by libraries and their users in accessing this information have led to groups of libraries working together and sharing information, goals and users. But visual arts librarians have not yet formalised a network of this sort, although preliminary analysis has shown the benefits of such co-operation.
