Kay: Ask your librarian about inter-library loans! I'm sure there's a way to get them into yours. I know in my state almost all the libraries are connected so they can share books AND you can return your book to any library within that system (and you don't have to get a new card to take out a book at a different library). I'm sure the librarians will be helpful...and they'll see that they are seriously lacking in Pratchett.
