Earlier this week ago I posted about Indies Unlimited March Madness, the feature of the month being experiences - usually bad - of independent authors at the hands of predatory publishers, Predominantly the vanity presses and new material has been posted on the site since my piece was published here.
The big player in the field is Author Solutions, but they are not alone and the predators aren't always the size of the proverbial Great White. Some are smaller, akin to the Piranha but the methods and principles are the same.
