An obscure copyright law is letting the Internet Archive distribute books published 1923-1941 / Boing Boing

"Section 108h of the Copyright Act gives libraries the power to scan and serve copies of out-of-print books published between 1923 and 1941; it's never been used before but now the mighty Internet Archive is giving it a serious workout, adding them to their brilliantly named Sonny Bono Memorial Collection (when Bono was a Congressman, he tried to pass a law that would extend copyright to "forever less a day" and was instrumental in moving millions of works from the public domain back into copyright, "orphaning" them so that no one could preserve them and no one knew who the copyrights belonged to)."
