We might want to revise that age-old saying about judging books by their covers.

The TerribleBookCovers subreddit has a few recommendations for you.

Highlighting the best of the worst in book design, title choice and overall presentation, the subreddit features a stunning collection of bad photoshop, creepy models and — err — niche hobbies.

From guides on knitting with dog fur to novel-length manifestos about the endless benefits of leeches, these books are basically impossible to not judge.

Take a look through some of our favorites below, coming to a bookstore hopefully nowhere near you (The Hobbit notwithstanding, of course).
