You should not touch historical books with gloves. It is generally correct to use your bare hands. The reason why you would wear gloves while handling a book is to protect you, perhaps because the book has been contaminated with hazardous chemicals or something.

Anyway.

It is also my experience that some people completely destroy their books. I don't know how it happens. I don't think of myself as careful with books. I shove them in backpacks, insert random objects to remember my place, take them outdoors, etc. Yet somehow, the books look much the same afterwards.

Part of this is just knowing how to pack books to avoid damaging them. Simple stuff like putting the spine down. If I'm going outside in the rain, keep the book out of the water. If I'm shoving something in my backpack and there's already a book inside, just check to make sure I'm not shoving something directly into the book.
