In the 1920s, Robert and Helen Lynd conducted a study of white residents of Muncie, Indiana. Their 1929 book reporting on the social dynamics of the town’s “working class” and “business class” became a surprise best-seller, inspired many followup studies, analyses, and retrospectives, and did much to shape how many educated Americans viewed “middle America”. The Lynds’ Middletown: A Study in Contemporary American Culture joins the public domain in 50 days. #PublicDomainDayCountdown
