The ALA appointed a committee to study censorship and recommend policy after the banning of "The Grapes of Wrath" and the implementation of the LBR. The committee reported in 1940 that intellectual freedom and professionalism were linked and recommended a permanent committee – Committee on Intellectual Freedom. The ALA made revisions to strengthen the LBR in June 1948, approved the Statement on Labeling in 1951 to discourage labeling material as subversive, and adopted the Freedom to Read Statement and the Overseas Library Statement in 1953.
