Abstract
Bibliography is a study that examines books externally and substantially, and has a role to offer basic knowledge in various fields of humanities, which make texts the main research objects. It is National Institute of Japanese Literature that has accumulated and disclosed the bibliographical data of early Japanese books as a useful data base. However, making a data base that contains substantial descriptions of books besides external data is tried by other organizations in recent years. In the future, overall data base together with data, description and image, which has the aspect of the history of the receipt and that of reading, will be required.
