You can get dustsheet covers - like they use on library books to preserve the dust cover. A book will have a lot more value with the original dust cover, so they are worth protecting. When I have a new Pratchett first edition, I remove the dust cover and place it as if it were a book, on my bookshelf, I then slip the book inside an old library book plastic cover until I have read it and then reunite book and dust cover. I have to say that with Raising Steam, I actually splashed out and got the Kindle version as well as the hardback. Consequently, the hardback has never actually been opened.
I've said before that it would be good for publishing if they offered a free Kindle download of the book when people buy a first edition hardback.
