Sistema Eragilea is a platform that allows artists to describe and catalog their own publications. Its database brings together the entries generated by its users and aims to add the publication entries that are already cataloged in other bibliographical sources.
At the end of summer 2016 we visited the abandoned asphalt mine of Arraia-Maeztu. Among the debris, we found an unusual publication —the Construction and Public Works Catalog published in Spain by the Technical File Services (S.A.T.) between 1958 and 1978.
