The Historical Archive CAB-IB is in a stage of organization, classification and digitization of its archives. The material contained in this archive is part of our country's historical heritage. To contribute to the preservation and to permit other researchers to access it in the future, it must comply with operation rules. For this reason all queries must be made in the archive facilities, to ensure the preservation of the material. This will help promote the application of appropriate methods for handling books and historical documents.
