Amazon, as you may know, had a lot of Kindle-related announcements. Go here for a rundown.

Among the announcements is the launch of X-Ray for Moves and X-Ray for Textbooks, which are exclusively available on the new family of Kindle Fire devices. X-Ray for Books is also now extended to the Kindle Fire devices.

“One year ago, Amazon introduced X-Ray on Kindle Touch, and customers loved it,” the company says. “Amazon is extending X-Ray to books on Kindle Fire, making it easier than ever for customers to learn more about the content they love by exploring the ‘bones of the book.’ With a single tap, readers can see all the passages across a book that mention ideas, fictional characters, historical figures, places or topics that interest them, as well as more detailed descriptions from Wikipedia and Shelfari, Amazon’s community-powered encyclopedia for book lovers.”

Here’s Amazon’s demo from last year:

“‘“X-Ray for Movies’ is a new feature that revolutionizes the movie experience by bringing the power of IMDb directly to movies on Kindle Fire HD, accessible with a simple tap,” says Amazon. “Without ever leaving the movie, customers can look up any actor in the scene or movie, see what other movies they have been in, and view photos, biographies and more. X-Ray is offered only by Amazon and is exclusive to the Amazon ecosystem. IMDb, an Amazon company for 14 years, is the #1 movie website in the world with more than 160 million monthly unique visitors worldwide.”

“Glossaries in print textbooks contain the most important information for students, but they’re placed inconveniently in the back of the book,” says Amazon. “And glossaries don’t always contain enough information for students working to understand new concepts. X-Ray for Textbooks solves these problems by integrating the glossary directly into each textbook page and by algorithmically assembling related data from Wikipedia and YouTube.”
