Joel Friedlander a.k.a. The Book Designer is one of my favorite resources for knowledge on self-publishing. He knows the business, and even better, he knows the technical side of things better than anyone else I follow.
He had a post on the 5th announcing his Printed Book Design 101 on BookBaby. It is a simple PDF he’s put together detailing all the little things to look out for when formatting a print book. I’m experimenting with all this, so print is not an immediate concern, but I know this will be one of the many books of my Self Publishing Bible when that comes.
