In addition to the index for my Expert’s series, I have also created 2 PDF indexes that cover my course books. There are two indexes because many students were taught using an older version of the course books with slightly different pagination.  If your Intro book has 50 pages and your Advanced book has 80 pages then use the v12 index. If your Intro book has 49 pages and your Advanced book has 76 pages then use the v11 index.
