The Book Contents Database allows you to search for books held in the libraries of the University of Tokyo by looking at their tables of contents or information taken from their summaries and dust jackets. This gives you access to the actual content of the books, which was previously unavailable through the conventional OPAC system. Approximately 229,820 volumes (Japanese:164,319 English:65,501, as of 2004.11) of books/materials held by the University of Tokyo can be searched.
