About three years back Amazon started beta-testing a new author portal called Amazon Author (not to be confused with Author Central). That new portal officially launched this past week with a somewhat confusing name and a new address.
Amazon’s author portal used to be at authorcentral.amazon.com, but it has now been replaced by a new portal at author.amazon.com. Along with the new address, the portal has a new look and new features.
