:: Copyright ::

The copyright of books available on this site has already expired in Japan. That is, the authors of books died more than 50 years ago (the period is longer if the special additional period for World War II should be considered). This does not mean, however, that the copyright of books has already expired in *all* countries in the world. So we would like to ask users to be careful for using materials on this site. Moreover, the maintainer of this Website retains copyright on all editing processes starting from taking pictures of books to processing the data for the Website.
