Authors on Amazon may have received an email in mid-September asking us to review or update the information in our Author Central profiles. "Author Central? What's that?" Wait; you don't have an Author Central account? Time to get one at Author Central.Amazon.com. From there, you can see all your titles, current rankings, reviews, add videos / book trailers and, as suggested in the Amazon email, establish or review your profile which is then visible to all Amazon customers. So add a nice picture.
You can also create profiles on the Author Central UK, French and German sites too. Is all that necessary; can't Amazon just show the data available in the .com site? No idea.

You can also link your blog, Twitter, Facebook and Pinterest accounts to your profile and see links to the other authors whom your Amazon customers have bought titles from. Looks like:
