My library doesn't have much in the way of books and the only book store in town barely carries 10 knitting books, so I get most of my patterns from the internet - mostly through Ravelry.
And I am Totally jealous that you have Custom Knits! I just adore Wendy Bernard. I don't thing I've ever seen anything she's designed that I didn't like. Next time I make it up the road to B&N, I am totally buying it. And when you run out of patterns from her book, check out the ones she has on her blog. http://knitandtonic.typepad.com/
