alda, (edited ) The people who designed Amazon's Kinde-to-Print self-publishing process don't know much about print, do they?
Here I am attempting to read a book that I just got in the mail and the margins on the spine side are so tiny that the first character in a line is barely visible and the margins on the outer side are good 2.5-3 cm.
I'm not sure if they've even seen a book before.
