Library.nu was shut down on the 15th of Feb 2012!
The site was invaluable to students and researchers around the globe.
As best said by cinnamon_oatmeal approximately 7 hours ago: “I can’t believe we figured out how to give everybody around the world instant access to millions of books and then decided it’s a BAD thing that needs to be shut down.”
This is a real loss to the global free exchange of knowledge, “as a graduate student, I use it almost daily!” ~ foldered.
