One of the materials provided by the Regional Ministry of Development and Housing to the digital information system was a databank. This databank includes a series of historic technical documents about public works in Andalusia which had been classified and reproduced.
In the same search engine, the databank combines four databases: road and rail bridge construction projects studied and described in the Administration’s General Archive; photographs of public works found in the same archive, in the National Library and in the Institute of Spanish Historic Heritage; films about public works in Andalusia, located and reproduced in the Spanish Film Library and the Ministry of Development’s Info-videographic Systems Unit; and written documents, maps and drawings of public works located and reproduced in the Archive of the Duchy of Medina Sidonia.
