I just started playing with this tonight, and it is *nice* and accessible. I think there is maybe one button that I have found that isn't labeled.
You can't beat the price either--free. I'm using it to catalogue all of my e-texts. It's really nice.
The link is below: Books 3.1.6 is now available. I hope the link works--it takes you direct to the download. If that doesn't work try: http://books.aetherial.net/wordpress/ Enjoy! Jane
