This is a limited re-edition of the original catalogue (33 v. in 34 v., published from 1932-1978). The set is now offered in two separate numbered language editions (for the first time in English, as well as the original French). The new series is essentially a re-publication of the original (issued with the approval of the Picasso estate) by the reconstituted publisher "Cahiers d'art", under the direction of its new owner Staffan Ahrenberg. Some revisions have been made including 30 updates, a small amount of factual corrections and a few deleted works plus meaurements being given in inches as well as centimeters for the English edition. The original catalogue is now also available for the first time in Chinese.
