The advice in the book referenced regarding Author Central no longer applies due to changes in Amazon policy on HTML
Spent a good part of the day battling with Amazon’s Author Central trying to get my product descriptions sorted. Ended up yesterday having to create a new American Profile because the UL version is different. Then I had to add the same information to each version of the book, Kindle, Paperback and Hardback. Then add various other bits for each version.
Finally, I was able to attempt to add the clever HTML described by Marcus Eigh in his book which can be found here Editors Note: No longer available)
I have managed to get some bits of the coding to work but not all.
