John Bowers, Elaine Sedenberg, and I have described how that might work, suggesting that libraries can again serve as semi-closed archives of both public and private censorial actions online. We can build what the Germans used to call a giftschrank, a “poison cabinet” containing dangerous works that nonetheless should be preserved and accessible in certain circumstances. (Art imitates life: There is a “restricted section” in Harry Potter’s universe, and an aptly named “poison room” in the television adaptation of The Magicians.)
