I have strong mixed feelings about this. I love purchasing go books, not only because I like them but also as encouragement for writers. But I'll take as example a book I own and IIRC you know something about: How to Improve on a 5x5 board, by Fukui Masaaki. How could I, on the west, legally (actually there's even no way to do it illegally) get this book?John Fairbairn wrote: ...

I was incredibly lucky a friend of mine was selling his whole go collection and happened to mention he had it in passing on a chat (since he wasn't going to sell this one, so it was not on the list.) So, now I have it. Likewise with a book on commented (in Japanese, sadly...) 9x9 games from a TV tournament (I think it's from there.)
