Analysis of information sources in references of the Wikipedia article "Melville Nimmer" in English language version.
Nimmer on Copyright is a 10-volume treatise that is considered the leading secondary source on American copyright law. For decades Nimmer on Copyright was the only substantial copyright treatise. There were four-volume and two-volume works, but only in 2007 when William Patry issued a copyright treatise was there a treatise of comparable length and depth as Nimmer's work.
