Thanks for this response. I'll have to work on this (but tomorrow... it's late at night for me at the moment). I can see part of what you mean: I can use, for example \index[myindex]{\it Book title} (Book Author) and get the correct result, but not sorted properly, so I have to understand how, as you say, to 'set the sort entry to the unformatted version' which is not clear to me at the moment. I'll tackle it on the morrow when I'm thinking more clearly!
