ARCA is an open portal giving access to relevant journals and magazines for the history of Catalonia which are no longer published. It is a collaborative repository of digital preservation promoted by the Biblioteca de Catalunya with the support of the Consorci de Serveis Universitaris de Catalunya (CSUC). Its goals are:

• To make access to periodicals easier. The users will find complete collections of serials, instead of wasting time searching for them in different institutions.
• To identify, retrieve and preserve the heritage of Catalan periodicals. The use of digital surrogates minimizes the risk of damage of originals.
• To increase the Catalan content on the Internet, contributing to making Catalan history, society and art expression throughout the years better known around the world.
• To promote the cooperation among institutions to complete collections, to improve services, to share resources and to make profitable use of the collections as well.
