A Cataloguing Plan was drawn up for non-catalogued materials. Approximately 220,000 volumes published before XX century were catalogued.

In the period from 2008 to 2011 were analyzed for scanning 145,000 books and 120,000 of them were scanned in the Google Scanning Center in Madrid. In this center were also digitized 80,000 books from the National Library of Catalonia.

This scanning center was small and were scanned only 300 books per day, not 4,000 books per day as in other Google scanning centers.

In June 2011 Google finished the operations in Madrid.
