The contents that we offer today are the result of having established a long term project, taking into account the diversity of the necessary and desirable documentation and the various institutions that guard them. Hence, to carry out this project, the Humanities Library has had the invaluable assistance of a number of libraries in public and private entities in Catalonia and the rest of the state. This surely will help then in the future steps of the project and we hope to expand the number of entities that provide us access to their funds.
