Hi Greg, thanks for the info. I don't need Aldiko, nor is it necessary. It was recommended awhile ago and that's what I've used.
Sounds like you went through the same thing I was going through - I setup the directories on my card as well, hoping to get Aldiko to utilize it. But as you see in this thread, it's not going so well.
I'll check out Coolreader. Besides, can't hurt to have more than one reader.
