Week 5 Thing 11

I found the site Lulu which lets you publish your own books and other things. It looks good, but it's foreign currency. I have had students ask me before about publishing a book, but I didn't really know off-hand where to tell them to "go." Does anyone know of another site out there that's here in the states that let's you do that? Lulu also says it's free with no publication fees, but of course, nothing's for free, but I don't think it was that expensive. Any comments?
I was also looking at Library 2.0. It looks good too, but I need to explore it a little further to see if I want to "join up."
