The Book Trailer Channel
Quick Look: Book Trailer Channel features promotional videos for books. Videos are generally between 30 seconds and 3 minutes in length, although some may run longer. Don't look for any book reviews or in-depth discussion here - the videos are very general and most appear to be designed as short commercials.
At the time of this review, only 18 book promo videos were available. The channel is currently looking for authors, agents and publishers to submit content to be showcased on this channel. More information is available under one of the channel's main menu items.
