This book enables a scholar or wizard to take his library with him virtually anywhere. Each of its 250 pages can hold an entire book - even a bulky, heavy, wizard's spellbook. To put a book into the tome of books, the owner simply lays the book on a blank tome page and speaks the filing command word. The book disappears, and an illustration of the book appears on the page, along with its title and a brief synopsis of its contents. A book cannot be placed into a page that already stores a book. To get a book out of the tome, the owner must open it to the book's page and speak the retrieving command word. Filing or retrieving a book is a full-round action. If the tome of books is destroyed, all its stored books are also lost.
