very good reference for Hanja
This is the only affordable and good reference book I have found on Hanja, there are other more modern sets around but they tend to be VERY expensive and may be hard to get. This small book is comparatively very cheap and easy to find, and covers all 1800 Chinese characters taught in Korean schools. Eventhough the last revision of this book was in 1982 it makes no difference at all, so don't worry about that. It shows the stroke order for each character. You should get this book even if you are a beginner, the sooner you start learning Hanja the better.
