Not sure if I'm in the right area but...
Is it possible to put a 'Customers who bought this book also bought' and 'More by this author' or 'Next in the series' lists into the last page at the end of book like Amazon and Apple do? I think it has something to do with adding a xml file to the book?
This post refers to it but unsure whether it is possible to put something like it in books of our own.
I also note when you convert kindle books into epub these features disappear as well...Does conversion delete these features? Can you change something so this feature doesn't disappear?
