The map of 20th century architecture archives in Spain

[EN] The Colleges of Architects in Spain date back to the 1930s. Among their duties was to keep copies of their members' work for the purposes of civil liability for projects, but custody was not indefinitely. After this period, many of these documents, graphic and written, have been lost, but those that remain bear witness to knowledge that new technologies dilute. A renewed approach to the management and communication of this heritage is urgently needed. We need to select and digitise paper projects to ensure their preservation and new life. We need to rethink tomorrow's Archives as technical and cultural tools in a society that increasingly recycles its buildings to make the planet more sustainable. To think about the future, it is appropriate to make an inventory of the present: a map of 20th century architectural archives. This communication will explore a first mapping of the archives of the Professional Colleges of Architects in Spain, their services and their archival collections (both paper and digital). It is true that some of these Colleges receive professional donations, new autograph collections that enrich those of heliographic copies. We will analyse the two most advanced depositories in Spain: Madrid (COAM) and Barcelona (CAC), without losing sight of other more recent ones (such as Valencia), to discover their capacity, services and new functions available online. These data will be cross-referenced with those of other institutions that have also started activities to collect and digitise selected documentation. This state-of-the-art analysis will allow an initial assessment of the feasibility of generating a network of interconnected archives. This network will foster the transformation of dead fonds into living materials of a Virtual Museum of Architecture (MVA) by revealing latent meanings and adding new layers of information and virtual visualisations.
