In 2007 the library conducted an analysis of their collections and storage spaces to ascertain the number of public domain volumes to be digitized and to obtain information on the facilities and accessibility in the locations.
Also the library prepared a Plan for Bookbinding and a Recommendations Guide to Select the works to be scanned.
The restoration department of the Complutense Library drew up a list of technical recommendations for repairing ancient century books.
As a result, it was possible to digitize many previously discarded volumes and improve their conservation.
The selection of volumes was based on three main variables: date of publication, physical condition of the item and fitness for scanning.
