User:Opencooper/20th-century black hole

The "20th-century black hole" refers to the gap in the public domain caused by overly restrictive copyright laws that came to affect works published since that time period. The term, coined by librarians, was first used in a general publication in a 2009 Financial Times article by James Boyle. The black hole particularly affects cultural institutions that have to preserve and make available collections that are still in copyright.
