My pal Ray Davis has written a great new rant about copyright:
William Blake didn't stop writing in 1818. It just looks that way because his antejerusalem manuscripts were destroyed after his death and before his most fervent admirers were born.
Our access to European pre-Christian culture depends largely on copyists' lack of judgment: wild-assed Christians, like wild-assed fundamentalists of other sacred-or-secular stripes, aren't shy about discarding the not-obviously-utilitarian.
A while ago, I picked up a "great young American poets" anthology from 1880 or so. I recognized only two or three names, and them not for their verse. Among the missing: Dickinson, Melville, and Whitman.
They might've stayed missing, too. Whitman developed a cult while he was living, but scandalized heirs could easily have snuffed posthumous printings. And under our current rules, Moby-Dick and The Confidence-Man wouldn't have entered the public domain until 1961, crimping the 1920s Melville revival.
I'm not worried about the Mouse or Gone with the Wind. Where there's money to be made and no insanity in the family, distribution will probably take place, with or without legal encouragement. And it's arguable, case by case, whether copyright hinders creation in the arts or promotes it or leaves it alone. But it inarguably supresses art (and embarrassing evidence) post-creation.
A reminder: there's about a month left until Lessig argues the Eldred case at the Supreme Court. If he wins, infinite extension of copyright will be declared unconstitutional and our world's intellectual future will be safeguarded.
(Thanks, Ray!)
