To that end, Barnes & Noble has launched a new discovery feature today called B&N Readouts. Update your mobile device with the latest versions of the Nook app for Android, iPhone, or iPad and you will enjoy a new opportunity to browse snippets of books.
B&N Readouts is a new section of the app where B&B algorithmically recommends books and news articles for you to try. You can limit the recommendations to your preferred genres, and easily scroll through the recommendations. If you see one that interests you, you can read a snippet which is about 2 iPad screens in length and takes from one to five minutes to read. If you like what you've read, you can share the snippet or you can download a longer sample.
There's more info on the B&N website.
It's an interesting concept, but I think Amazon did it better when they added the Book Browser section to the iOS app last December. This let you browse through all the samples in the Kindle Store, and not just snippets. It also has a much better name, but it doesn't have the news articles you might find in B&N Readouts.
