Basic Life and Death Dictionary (Online book in Japanese by Eba Hiroki)
[1] Note that the Chinese, Japanese and Korean names translate as "death (and) life", not "life and death".
[2] zinger: Harada's problems are the best I have found on the web - always very realistic game positions. Beware the difficulty labels, however: "elementary" can be tricky, and "intermediate" can be quite hard, at least for me.
unkx80: I would say that his "elementary" problems often verge into the intermediate/advanced territory. But it is one of the best problem collections.
