Barnes & Noble is trying again with a full-fledged offering of digital audiobooks, available for single-title sales or through a monthly subscription priced at $14.99. They promise a catalog of over 300,000 titles. In a bit of brand confusion, the new initiative is called Barnes & Noble Audiobooks, though it’s tied to the all-but-dead Nook brand, since customers will listen to their audiobooks through the Nook mobile apps. (Separately, BN recently had to discontinue in-app purchases through their Android Nook app, after Google changed their terms to require the use of the Google Play billing system.)
