Massachusetts obscenity law is modified.

Under the new law, books cannot be banned for containing obscene passages, only for being obscene in and of themselves. The campaign to modify the law was led by Edward Weeks and prompted by the banning of Upton Sinclair’s 1928 novel Boston: A Documentary Novel of the Sacco-Vanzetti Case. A new state making the selling of obscenity by book sellers a civil rather than criminal matter is passed in 1945.
