Their supposed to be organized?
Seriously though, on my Kindle it's pretty simple. I have
Games and Apps
Writing
Guides and Dictionaries
Vegan, for cookbooks
Fiction Samples
Non-Fiction Samples
This is just for stuff I want to permanently have access to (except for samples obviously). Everything else falls onto the main page. Since I keep all my ebooks either in Calibre or at Amazon, as I read things I delete them from the main page.
Oh, and sorry for intruding into nook land
. I didn't realize this was a nook specific thread.
