Clayton has a LOT of books and many are hardcovers with book jackets. He always seems to pull off the covers which leave them more vulnerable to wear and tear. So, I used acid free tape to make them stay on the books better.
I made 2 inch pieces of tape and 1/2 inch pieces. I put the small piece sticky side down on the 2 inch sticky side. This way the book will not be stuck with tape, just the dust jacket. I placed the strips evenly on the jacket edges on all four corners.
