Is there any author who wrote more than 150 books or novels?

While it's difficult to definitively say who has written the *most* books, there are several authors who have written over 150, and some even more than 200. Here are a few examples:

* James Patterson: With over 200 books, Patterson is known for his prolific writing, often collaborating with other authors.

* Barbara Cartland: She published over 723 romance novels!

* Agatha Christie: She wrote over 66 detective novels, 14 short story collections, and several plays.

* Isaac Asimov: Asimov penned over 500 works of science fiction and nonfiction, spanning various genres.

There are many others, depending on how you define "books" (including short stories, plays, etc.). It's worth noting that prolific writing doesn't always equal quality, but these authors have certainly had a significant impact on the publishing world!
