I just use Calibre for organizing and editing metadata. To read i just use whatever epub or pdf reader. For me , Calibre does everything I need. Every book organized by group, then author. Every book with its book cover. If it doesn't have one Calibre can generate for me etc. And on top of it all, Calibre generates a neat folder structured with everything properly named. When you have hundreds of books it is a must.
