This paper presents the analysis of the results of research work carried out for several years regarding possible ways and models for the procedure in cataloging graphic documents. We start with a thorough preliminary
analysis on the existing rules, to which we understand it is subjected the cataloging of graphic documents, drawings and maps; and we suggest some ways to improve them.
The management of documentary sources involves establishing mechanisms for the collection of parameters that are explicitly concerned with the cataloging rules. In the absence, in many cases, of standardized
cataloging models of maps, drawings and plans, we propose a protocol based on the current rules, suitably modified basing on the experience of comprehensive cataloging work on a series of drawings and plans of
Seville Cathedral, dating from the sixteenth to the twentieth centuries
