TED Books, the publishing arm of the TED Conference, has launched its new iOS app for eBooks. The publisher announced the beta edition of the app a couple of weeks ago, but it went live in iTunes yesterday.

The app launches with 16 current eBooks and new titles will be released every two weeks. AppNewser has more: “The app lets readers buy eBooks a la carte for $2.99 each or readers can subscribe for $15 for a three month subscription, which gives readers access to all of TED’s eBooks.”

Here is more from the TEDChris blog: “the app retains the linear narrative thread that makes reading so appealing. Some ambitious attempts to create ebooks on a tablet have somehow abandoned this. When you snuggle up with a book, you want the author to take you on a journey. You don’t want to have to make constant choices as to what to look at. If you think of a book as a wonderful train journey, some ebook apps effectively boot you off the train and make you travel by rental car.”
