ShelfAwareness: Daily Enlightenment for the Book Trade. OK, so this isn’t technically a website or a blog, it’s a daily e-newsletter, but hey, if you don’t want to bother subscribing to it, you can go to the site and just treat it like a blog by reading the daily issues.
ShelfAwareness is meant for the book trade, so you’ll get insider news, information on upcoming books, and pertinent ads from publishers. A ridiculous amount of information in a handy daily little package. There is also a bi-weekly newsletter for general readers, so consider signing up for both.
