Why do paperback covers lift up?

Question

I have a few new paperback books and when I read them, the front and back covers seem to lift up in the air for some reason. Does anyone have any explanation to this and how I can make it flat?

Answer 1

I know what you mean, I hate that. I usually put another book (or anything heavy) on top of it, and the next morning it's usually flat again.

I don't know why they lift up, but if you don't want them to, and don't mind spending the extra money, you could purchase hardcover books.

Answer 2

It's the heavy plastic face... does not expand in a moist climate, but the cardboard on the other side does. That causes it to curl.

Keep it tight in a bookshelf, or place a hardback book on top. That will minimize the curl.

Answer 3

I'm not really sure, Perhaps the wind blows them up or if the air is cool, Makes them crisper than usual...Other than that I have No idea.

If you don't mind spending a little Extra buy some Hardcovers or a Book Press to flatten them?
