HarperCollins Borrows from DVD Model, Adds Bonus Features

One of the biggest advantages that comes with viewing a DVD is the behind-the-scenes features that makes buying the disc worthwhile. Now, HarperCollins and its Perennial imprint have integrated the concept into the realm of literature.

A series of paperback books have been released as "P.S. Titles," and each contains a 16-page supplement with 'behind-the-pages interviews,' essays, articles, photos and illustrations that give readers a deeper understanding of the author's inspiration.
