Kahle v. Gonzales was argued by Larry Lessig on Nov 13th at, maybe 10 or 11AM.
What is at stake is libraries being able to have out-of-print books on their digital bookshelves as they have out-of-print books on the physical shelves we grew up with.
Given the depth of the questions from the judges, they have not seemed to have thought about it much. Hopefully that is not true. Fingers crossed.
