The New York Times has announced the launch of two publishing programs--New York Times short e-books co-published with the digital startup Byliner, and TimesFiles with Vook.

In collaboration with Byliner, The Times will co-publish up to a dozen New York Times / Byliner Originals in the next year featuring narratives in areas in which The Times has reporting expertise including culture, sports, business, science and health. While sometimes growing out of related Times reporting, the titles will offer original content that is not available in the paper or on The Originals will range from 10,000 to 20,000 words in length and are designed to be read in one sitting.

“Snow Fall: The Avalanche at Tunnel Creek” by New York Times reporter John Branch, the first Times / Byliner Original, tells the story of skiers caught in an avalanche. It expands on an article that will publish in the December 17 paper. It will be available for purchase on Monday, December 17 at online retailers including (Kindle), Apple (iBooks), Barnes & Noble (NOOK), and for $2.99.

Future contributors to The Times-Byliner collaboration include Pulitzer-Prize-winner David Leonhardt, The Times’s Washington bureau chief, and Pulitzer-Prize-winner James B. Stewart, The Times’s “Common Sense” columnist and author of Den of Thieves, among other books.

TimesFiles are curated selections of articles from The New York Times archives, assembled into compelling narratives about a particular topic or event. Built in collaboration with Vook using the Vook e-book publishing platform, the TimesFiles collection will have 25 e-books available on December 17, with many more expected to come in 2013. TimesFiles will be available starting at $1.99 from (Kindle), Apple (iBooks), Barnes & Noble (NOOK), and Launch titles include “The Fall of the Berlin Wall,” “George Steinbrenner and the Yankees” and “The Life and Films of John Hughes.”
