I've already searched all the major online bookstores, they do not have them and my local bookstore can only supply books that are available in the Netherlands. Furthermore, I have tried to obtain as much details as I can but since I do not have a copy of one of these books I do not know the publisher. My post was/is intended to find a place where I might order these books or otherwise find someone who can provide me with as much information as possible concerning ISBN number, publisher, year(s) of publication, number of editions and prints, etc. If these books are no longer available in print I hope that someone can provide me with a secondhand serie or (if nothing else is available) a photocopy would be better than nothing. If you know of any online bookstore etc. who carries these titles or other aikido books, please let me know.
