In the UK we (or at least I) never used the exercises from the text books - the lecturer sets their own questions and exercises.

So the exact page layout of the text books doesn't matter, and you can use any edition.

In general text books just seem to be less of a big deal in the UK. I remember reading all the classic text books, but the course didn't revolve around them. You could often pick which text books to read out of a selection.

And you just get them from the library.
