Ah, the public domain: Where creative work is supposed to wind up after a limited period during which the creator has exclusive control over distribution and copying. An ever-growing pool of literature, music, photography, video and art that we can use not only as inspiration but also as the direct basis for new works, annotating, deriving or just plain redistributing.
What a wonderful thing.
Too bad it’s basically been frozen for quite a few years now, with almost nothing new entering the pool (except government publications—which start in the public domain) and things tagged with the Creative Commons CC0 license. Oh, and probably a few cases where a creator’s been dead more than 70 years and has works produced since 1923.
Not only has it been frozen in the U.S., there are laws and treaties that would appear to shrink the public domain pool—which should, by any rational reading of the Constitution, be flatly unconstitutional.
