There's something undeniably creepy about big, expansive libraries. The hushed whispers, the almost artificial quiet, and the smell of dusty tomes combine to create a surreal experience. But when it comes to creepy libraries, Harvard University might take the cake... you see, at least two of its books are bound in human flesh.

A few years ago, three separate books were discovered in Harvard University's library that had particularly strange-looking leather covers. Upon further inspection, it was discovered that the smooth binding was actually human flesh... in one case, skin allegedly harvested from a man who was flayed alive. Yep, definitely the creepiest library ever.
