Ever since I was younger, I always enjoyed walking through Barnes & Noble to find books with trivia, random facts, and hypothetical situations. One of my favorite trivia books growing up was actually The Encyclopedia of Everything Nasty by Joy Masoff, completely filled with gross facts about snot, maggots, pus, and more. Definitely weird, but super interesting to 8-year-old me.

Now as an adult, my bookshelves have trivia books scattered among my other fiction and nonfiction selections. If you’re anything like me and enjoy learning how “missionary position” got its name or why our fingers wrinkle when wet, here are some great books for a random fact of the day.
