Two new titles are available on Kindle, and a new book from one of the big five, The New Yorker, is also available for sale on Amazon.
The titles, which include a new collection by Stephen Colbert, have not yet been officially announced.
A spokesperson for the Big Five said the new titles, based on The New York Times best-seller list, were not included in the new print and e-book offerings.
Big five publisher Amazon announced last week that it will open up to a new print book publishing platform, Kindle.
The publisher said that it was aiming to launch more books on its new platform in 2019.
