I am one of the Wikipedia editors tasked with repairing defective ISBN's. I would ask you to please go back and review the ISBN contents listed on the Federico Colpi page. I have been unable to locate the reference books in question. It appears to me that one number has dropped from the bulk of majority of the ISBN's shown. We would appreciate your assistance in this matter.Ekotkie 03:36, 6 January 2007 (UTC)
