For many years copyright was a backwater of the law. Perceived as an esoteric and narrow field beset by hypertechnical formalities, the discipline and its practitioners were largely isolated from developments in scholarship and case law in other areas. There were exceptions, of course. Well before the explosion of intellectual property litigation in the last twenty years, persons such as Zechariah Chaffee, Jr. and Judge Learned Hand brought learning and broad perspective to copyright. But by and large copyright looked only to itself for guidance.
