A concordance is like an exhaustive index. I have prepared a concordance for the Book of Mormon. It consists of references for every word which occurs less than 250 times in the book of Mormon. This makes it short work to look up any verse or even do topical searches. I can give you the concordance in loose-leaf format for $20 dollars, plus shipping, or an additional $10 if you're ordering it together with the Book of Mormon.
