Book titles, if they were named today:

Then: The Gospel of Matthew
Now: 40 Days and a Mule: How One Man Quit His Job and Became the Boss

Then: Philosophiæ Naturalis Principia Mathematica (Newton)
Now: Why Do Apples Fall Down and Not Up? Answers From The Cutting Edge of Physics

Then: The Catcher in the Rye
Now: PARENTS BEWARE: Your Angsty, Depressed Teenager may be Drinking to Extremes and Surfing Porn on the Internet

There’s a note in the comments from a guy in publishing, who says that books with simpler titles actually do fare better … though if only because they’re easier to find on Amazon. (via)
