What is a Key Phrase?

Key Phrases are select phrases from books and movies. A key phrase can be a Capitalized Phrase or Statistically Improbable Phrase found inside a book in the Search Inside!™ Program; or it can be an actor, director, or plot keyword occurring in movies available on Amazon.com.

Capitalized Phrases, or "CAPs", are people, places, events, or important topics mentioned frequently in a book. Statistically Improbable Phrases, or "SIPs", are the most distinctive phrases in a book. Just as CAPs and SIPs give you a quick glimpse into a book's contents, a movie's actors, directors, and plot keywords give you more information about that movie.

What is a Key Phrase Page?

The Key Phrase Page for a phrase shows you information, products, and other key phrases related to that phrase.
