I'm the librarian at my house, and Scotch Book Tape has saved the life of many a book here!
This tape is great for giving extra strength to the spine of that favorite paperback book. It reinforces the corners of the covers as well. When my friends ask how I keep my paperbacks looking so new, I tell them Scotch Book Tape is the answer.
When toddlers ripped an entire book from its hard cover, Scotch Book Tape came to the rescue again. The contents never came loose again; the tape never cracked, not did it ever change color.
And outside the home library, the uses are endless. Needless to say, I'm sold on this Book Tape!
