Eric Moon, a progressive, even radical librarian who for more than 50 years has served his profession as goad and prod, devoted practitioner, gutsy journalist, magnanimous publisher, revered and resented association leader, smug antagonist, beloved mentor and antic crony, has been at the center of almost every important debate involving the shape and direction of the library profession in North America since the late 1950s and well into the 1990s, and before that for some years in England. Editor of Library Journal, president of Scarecrow Press, president of the American Library Association, Moon has had an opinion on all of the heated issues.
