The mandatory professional internships and all that this brings with it guarantee a balance between reflection of a theoretical and practical nature and knowledge of the 'nuts and bolts' of the jobs in question. Interdisciplinary constitutes a fundamental aspect of the training because along with specific courses come other courses borrowed from the faculties of law, economics, social and political science. The learning set-ups are also highly diverse because they include in particular library visits and visits to archive and documentation centres, publishing houses and commercial and cultural businesses.
