The Kindle MatchBook is now live online.

The program gives Kindle users the option to buy—for $2.99, $1.99, $0.99, or free—the Kindle edition of print books they have purchased new from Amazon.

Kindle MatchBook was first announced on September 3rd. At that time Amazon said about 10,000 titles would be available. Since then the program has added more than 60,000 titles.

From Amazon.com:

Over 70,000 books are enrolled in Kindle MatchBook, with more being added every day. Now customers can visit www.amazon.com/kindlematchbook to see all of their print books that are eligible for the Kindle MatchBook edition. Customers can also see when a book is eligible for Kindle MatchBook on the book’s detail page.

Since then [when the program was first announced], thousands of popular books like Heaven is for Real, The Things They Carried and The Way of Kings have been added from major publishers such as HarperCollins, Macmillan, Houghton Mifflin Harcourt, Amazon Publishing, Wiley, Chronicle Books, and Marvel, as well as thousands of titles from Kindle Direct Publishing authors like The Walk by Lee Goldberg and Falling Into You by Jasinda Wilder.
