This is fascinating stuff. Thanks for posting it. I was left wondering: What if any, significant differences arise on the YA side of the house?

For instance, often the books are shorter, so therefore probably cost less to print--is it enough less to affect marketing efforts/advances, etc.? I also suspect the distribution of buyers is skewed more heavily toward libraries and big chains than independents and general retailers. Do YA books tend to have a better sell-through, or the same?

Thanks again for such an educational post!
