Paul, Yes, this wheel you've invented is pretty good, but I'm using a slightly different vehicle. I don't normally mention this in the context of a forum, but I've no sight, and use a screen reader. Whilst I would like to get out of writing anything, the request from my friend is pretty specific. He wants all entries marked, then wants to create the index himself. The pattern you've recommended works fine, but I misled you (screen reader again). the books actually have a space between number and book, i.e. 1 Pe. Not to be defeated, I tried putting a \s into your pattern, but it found no results. on googling tutorials, I've found some rather patchy results. I am very happy to invent this particular wheel, and before reviving this thread, made every effort to find a solution.
Thanks,
David
