You can narrow the search to only Sourcebooks titles by adding the word "Sourcebooks" to your search terms. They do a good job of formatting, which most PubIt titles do not. Or just click here and see if the URL for my search works for you:
You can, however, get a nicely formatted FREE version of The Black Moth directly from the Girlebooks website (meaning you'll have to go to their website, download to your computer, and sideload to your Nook). I prefer their free classics to Gutenberg's when they are available, since they seem to do a good job of formatting.
I'm having a great time going through all these books... It's so tempting to spend $100 (well, $90, since I already have a few of them) on ebooks this week, but I guess some restraint would be a good thing.
