Absurd licensing terms imposed on public domain works by libraries and museums

From BoingBoing

"Keneth Cerws' published studies take copyfight to libraries and museums where restrictive - often absurd - copyright claims and licensing terms are forced on those requesting images of art works and scans of books and documents where the original work long ago entered the public domain, often decades or centuries ago. This raises relevent questions about fair use, academic and research use and how we treat copyright for new images and renderings, often digital images, of old works that many consider vital pieces our common human history, heritage and cultural commons."
