From the site:
Here at AUTHORSdB we’ve formed the only database of authors, including social media, book listings and much more, for today’s mine-field of thousands of aspiring and established writers.
We are a dedicated website that helps authors for free. Why free? We have a few Angels who simply want to see authors flourish. Readers no longer have to Google from several different websites to find out more about a particular author — it’s all here.
We are tweeting fools — We tweet about anything related to our members, whether you are #1 in Amazon, trending in social media or launching a new book. We tweet and retweet your news. Let us know what’s happening!
