Discover Terry Pratchett: The First Five Discworld Novels

One of the best story tellers of all time! Humorous, witty and enjoyable!

I've got most of the Discworld books, in a variety of paperback, hardback, old and new. I thought it would be nice to start compiling a definitive set of them, from the beginning. So I was not at all impressed to receive the first bundle with the books being different sizes and shapes. That's not how they were advertised. Will the following collections be the same?
