 If an award were given for the single most important intellectual development in the field of human service in the past one hundred years, normalization and SRV would have to be two of the top contenders.In fact, recognitions along these lines were given.In a poll of mental retardation leaders, Wolfensberger's 1972 book on normalization was selected as the most influential book in the field since 1940 from among 11,330 books and articles, and his 1983 article that introduced SRV (Wolfensberger, 1983) was cited as the seventeenth most influential publication in the field (Heller, Spooner, Enright, Haney, & Schilit, 1991).
