I know what you guys are thinking... OMG where is my index?!?!?! Worry not. Because of editors changing textbook companies, the indexes have become confusing.

There can often be a lot of cross over for lesson concepts. So...

If you are looking for the 2017 Judy Yin edition, you can find it under the BiSangGyoYook Mass Index here:
