Today, January 4, 2014, is the publishing date of the new book The Beatles: Six Days That Changed the World, written by Bill Eppridge and edited by Adrienne Aurichio. The book was featured on the New York Times' LENS blog on February 3, 2014.

The book contains many never-before-published photographs of the Beatles from their first trip to the United States taken by Bill Eppridge, Life Magazine photojournalist of renown who passed away in October of 2013. Eppridge captured them in candid moments in hotels and on trains, at press conferences, and taping the Ed Sullivan Show. After Life published several of his images, the negatives went missing for years.

An essay by Adrienne Aurichio about the significance of the images can be found on the CBS News blog.
