Disney's Wonderful World of Knowledge Series

"DISNEY'S WONDERFUL WORLD OF KNOWLEDGE" is an updated and enlarged English version of an encyclopedia heretofore printed in the Italian language by ARNOLDO MONDADORI EDITORE, MILAN and entitled (in English Translation) "DISNEY ENCYCLOPEDIA" This book shares an ISBN (ISBN #0-7172-8164-7) with another book entered in Goodreads, entitled "Treasures of the Earth (Disney's Wonderful World of Knowledge)." As both volumes belong to a larger set of books, it is possible that this ISBN was issued to the set as a whole, though this is currently unverified.
