Here is my first stabs at playing with iTunes and eBooks.
So first what I am doing to keep things easy to find is creating separate playlists in the eBooks area for each author and/or series.
Then I making sure to fill out the meta data adding in things like Grouping = Series and Composer = Publisher.
You can then use those special categories for sorting through your stacks in the “all your” Books category you see up at the top.
I am still working on this way of using iTunes with something other than music files so I will keep you guys in the loop if I run into any issues.
