In 2006 the Junta de Castilla y Leon started the ‘Plan Libro Abierto’ (Open Book Plan), aiming to promote the work of writers and editors of Castilla y Leon on every possible level and in different fields, bearing in mind that this region is the main international reference in the apprenticeship of the Spanish language. The Junta de Castilla y Leon’s sponsorship of Hay Festival focuses on this, as one of the most important literary and artistic events on the occidental cultural landscape.
