In recent years an ambitious program of action has been developed regarding the centre's most valuable documentation, especially the Registers of the Royal Chancellery (description, restoration and reprography through microfilm or digitalisation). All the digitised ones from the last ten years can be consulted online, since the resulting image has been linked to the revised description in the Portal of Spanish Archives (PARES).
At present, the information introduced to PARES in previous years through a bulk upload of existing manuscript and typed description tools is being reviewed. In parallel, new descriptions are being added and existing ones expanded, following the international ISAD(G) and ISAAR(CPF) standards, as well as the rules for the creation of access points of the General Sub-directorate of State Archives.
Likewise, the fields and levels of description are being reviewed and modified to facilitate the international exchange of information and facilitate the connection of PARES with the European Archives Portal through the APE project.
The description of the Arab Letters collection has been completed.
The description of the Royal Letters of the time of Ferdinand the Catholic has been reviewed and completed.
