Happy public domain day: here's what copyright term extension stole from you in 2015; BoingBoing.net, 12/31/15

Cory Doctorow, BoingBoing.net; Happy public domain day: here's what copyright term extension stole from you in 2015:

"When Congress amended US copyright law in 1976, they extended the copyrights on works whose creators had produced them with the promise of not more than 56 years. Since then, almost nothing has entered the US public domain.

Every year, Jennifer Jenkins and Jamie Boyle at the Duke Center for the Public Domain list out all the works that today's artists would be free to work from -- as the creators who got their copyrights extended in 76 did -- except for the retroactive extension of copyright terms.

This year, we lost a lot of good stuff."
