It's a pretty simple program for bloggers. You pick out a book to review from their site. They send you that book for free. You write a review on your blog and link it to their site. Repeat.
Knowing that my book reviews may not be extremely interesting to all of my regular readers, I am only going to post them on Sunday, which has traditionally been my day off. I expect I will do about one per month, maybe two, depending on how fast they ship. By putting the review on Sunday, I will not be displacing my regular content.
Now that I'm with BlogHer, I am a little more limited about my reviewing capacity, but their rules state:
"You may also accept for free and review any product(s) with a retail value of under $40 (U.S.) as long as you properly disclose that you were given the product."So, I am disclosing that I will review these free books, and am recommending that if you are interested in free books, you might want to check out this program, even if you're with BlogHer.
