I signed up for the Absolute Write forums – http://www.absolutewrite.com/forums/. I had been a longtime lurker under another user name, but this time I dove right in. It’s really a great resource for finding current information about writing, publishing, marketing and all of that. If someone there doesn’t have the answer to your question, they’ll at least have some strong opinions about it. They have subforums for all genres and one specifically for self-publishing and another for promotion, so I definitely encourage you to check it out. I had to be manually approved to start posting and to edit my profile, but I was approved in less than a day.
And the reason I bring up these forums now is that the postings in there led me directly to the Goodreads Making Connections group. Before, I was sort of vaguely aware you could offer your book to reviewers on LibraryThing and Goodreads, but I hadn’t really looked into the logistics. Turns out the Making Connections group is actually a pretty easy and friendly way to go about it.
The reviews are not specifically Goodreads reviews, but also Amazon and other sites as well.
