The basic mission of the CIDA, a body that is dependent on the Department of National Archives, is to publicise the wealth of content in Spain's Documentary Heritage and bring it to a wider public. The CIDA was created by Royal Decree 2258/1977, of 27 August, on the organic structure and functions of the Ministry of Culture.
One year later its functions were outlined in the Ministerial Order of 7 August 1978 on the structure of the Documentary Information Centre . Its main aim is to establish an archive information system, co-ordinating the informational aspects of documentary heritage, as well as bibliographical information concerning professional archivist literature.
The CIDA is also a member of the European Network of Information and Documentation on Latin America, REDIAL.
