Aah, I haven't tried that. I didn't know that there was such a thing as Nook for PC. Thanks!
They aren't books that I purchased -- they're files I wrote myself on my computer, put on my Nook, then marked spots I needed to change with Highlights and notes.
Thanks again -- that Nook for PC thing sounds like it might work. I'd rather be able to just export them as a text file or something but at least that could get the information onto my computer. I can go from there... who knows, like you said I might be able to find a way to locate the information once I have it on a full fledged machine.
