I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I've been going through books donated to the library I work at. So much dust, dirt, and squashed insect life. I think insects are #2 in the list of things I hate about badly-cared-for library donations. Mold is probably #1. I once tried to pick up a donated book only to discover that mold had glued it and two of its neighbors together. So. Gross.
