Obviously not much for a tsumego problem. But then, are these two books from Segoe merely collections of tsumego or does he explain some strategic concepts as well (thereby requiring more verbage)?

For comparison, Segoe's tesuji dictionaries are accessible to non-Japanese readers because they provide illustrations of the basic suji and increasingly difficult problems to test the reader's understanding. An original Japanese-language version of, for example, Kageyama's "Lessons In The Fundamentals of Go", while considered to be notably helpful in strengthening play, would have been far less useful to an English-speaking audience had it not been translated.
