Novelty
"Borrowed the work must indeed not be, for a plagiarist is not himself pro tanto an ‘author’; but if by some magic a man who had never known it were to compose anew Keats’s Ode on a Grecian Urn, he would be an ‘author,’ and, if he copyrighted it, others might not copy that poem, though they might of course copy Keats’s."Sheldon (CA2 1936)
