Does anybody know anything about the Nihon Kiin Great Joseki Encyclopedia? Most important is how up-to-date it is. Supposedly it is the most comprehensive joseki reference but if it is the most comprehensive from 40 years ago that's not too helpful.

The other things I am interested in are whether or not it shows followups to the joseki, and whether or not it shows full-board situations in which the joseki might be useful.

The reason I ask is that Yutopian has it at a (comparatively) low price in its Chinese form and I'm considering buying it while it's even vaguely close to affordable.
