Yeah - I'm thinking you might be happier with something specifically designed for books and documents. Books can have sharp corners so good fit is essential. Most panniers are intended to store soft compressible items like clothing. You might also be able to pick up something more generic and line it with closed cell foam. Suggest you bring the largest item you're likely to want to put in it with you or at least measure them.
