Query: First choice reference

With this and the "For Dummys" book on knitting, I have found every answer I needed. I am self-taught and I've found no other knitters in my area. That makes this kind of book is essential for me - and it satisfies. It has an excellent index which is very important to me when I need to find a technique or description of an obscure stitch in the middle of a project. After I got it from Amazon, I intended to scan through just to get a feel for the contents of this reference work but I found I continually stopped to read about things I would not have known to ask about. So, the book teaches and answers. Maximum value for me.
