The Independent Printing Resource Center in Portland is hosting a 24 hour reading of Moby Dick starting at 17:00 on 11 Feb 2011. I like the explanation of why they’re doing it:
When first published, Moby Dick was a near flop. It remains a totem to the importance of small, independent publishing for keeping alive great works ahead of their time.
It starts at Powell’s and moves to a mystery location from there.
