United States v Rumley 1953. In the early 1950s the Supreme Court found it unconstitutional to convict a bookseller for refusing “…to provide the government with a list of individuals who had purchased political books.” Justice Douglas observed, “Once the government can demand of a publisher the names of the purchasers of his publications . . . [f]ear of criticism goes with every person into the bookstall . . . [and] inquiry will be discouraged.”
