One of my key sources of ephemera, anecdotes, and useless information was my treasured subscription to the 1980s Time-Life book series, "Library of Curious and Unusual Facts." One slim volume of the series was called World of Luck, and contained nothing but stories about incredible coincidences – the kind of thing where someone finds a rusting pair of dog tags on a beach, tracks down the original owner, and discovers that they worked in the same office or whatever. There was plenty of Unsolved Mysteries / Ripley's Believe It or Not type stuff circulating during that era, but I really loved these books because the stories were true (and not in the "three witnesses confirmed the anal probing by aliens" sense).
I just witnessed a World of Luck moment up close.
A man in Oklahoma City bought a used copy of The Grapes of Wrath. He saw a name on the inside cover that matches Question Cathy's name (a last name neither super common nor entirely uncommon). It turns out that she gave the book away to Goodwill in Texas, it somehow ended up in Oklahoma, and it was purchased by one of her work acquaintances…who also happens to live two doors down from her (Question Cathy's) brother.
He contacted her via social media and was like, QC, I don't know how to say this without sounding crazy but I think I somehow have your high school copy of The Grapes of Wrath. It sounded like some kind of weird come-on and then…well, he did. He really did.
The world is really kind of strange sometimes.
