Oddly, the Amazon web pages for KindleGen and Kindle Format 8 that I have used in the past are no longer present. (At least for me.)
KindleGen: https://www.amazon.com/gp/feature.html?docId=1000765211
Kindle Format 8 Overview: https://www.amazon.com/gp/feature.html?docId=1000729511
I wonder whether this is a temporary problem or if it reflects an intentional change by Amazon to remove the more technical documentation related to building books for Kindle. Their emphasis these days is on Kindle Previewer 3 and Kindle Create.
