Cover your books

I like to keep my hardcovers in good condition. There many different covers you can use to protect the dust jackets. I wouldn't use anything that uses glue or tape. I use the one that has the plastic cover front and paper back that you fold to keep on the book. I get them from my local used book store. http://www.shopbrodart.com/site_pages/bjc/ should also have them. Also, as a side note, I never ever put stamps or write inside my book. It also lowers the value of the book.
