“Valuable resources are being lost to students, researchers and historians because of sweeping changes in copyright law, according to digital archivists who are suing the government. These resources — older books, films and music — are often out of print and considered no longer commercially viable, but are still locked up under copyright. Locating copyright owners is a formidable challenge because Congress no longer requires that owners register or renew their copyrights with the U.S. Copyright Office.” The plaintiffs in the lawsuit want the right to create a digital archive of such “orphan works” for public use.
