From those posts, you can continue on to others.
The gist of Kim Bofo’s post is that bloggers should disclose that the book they are reviewing is an ARC or free copy from publisher/author.
Like MJ Rose said in her post (link above), I just can’t see someone selling out for USD$23.95.
So that makes the disclosure unnecessary.
I do mention in my reviews that a book was free or is an ARC.
But this is my blog, a little part of the internet that belongs to me. I RULE here. It feels right to me, so I choose to do it.
I do not expect that other reviewers follow suit. It freaking amazes me that there is someone who does!
