X-Ray (Amazon Kindle)

X-Ray is a reference tool incorporated in Amazon Kindle Touch and later models, the Kindle Fire tablets, the Kindle app for mobile platforms, Fire Phone and Fire TV.

General reference information is preloaded onto the Kindle device, so that when the feature is used, there is no need to access the Internet (which can disturb a user's experience). The information can range from encyclopedic content to information about actors featured in a film.

X-Ray lets users explore in more depth the contents of a book, to "get to its bones". Users can touch a word to launch either a dictionary definition or a more in-depth explanation provided by Wikipedia or Shelfari. X-Ray does not connect to the Internet to retrieve information. Instead, it accesses pre-loaded files with relevant information.[1]

The function of X-Ray operates like a concordance, listing most commonly used character names, locations, themes, or ideas, which are sorted into the two main categories "People" and "Terms."[2] Readers can use it to look up first occurrence of characters, which is often helpful in many-charactered novels.
