I do have a follow up question: I used a program to generate the unique word list for the entire book, and the list showed separate listings for capitalized, non-capitalized, singular, and plural instances of the same word. I included these four varieties of the same word in the creation of the index, so as to capture all occurrences of these words. So currently in the index, for one word -- say the word, "book" -- there are four listings: Book, book, Books, books. I'd like to collapse these four listings into one -- "Book" -- and include all the page numbers for the four varieties in a single listing. Does this need to be done by hand after converting the index to a text file? Or is there a better way to do this?
