In 1946, Brown helped established the Committee on the Practice of Democracy (COPD) in Bartlesville. The COPD worked to improve "relations among people of all race [and] to foster improvement of conditions arising out of discrimination based on race, creed, or color." Later the same year, the Bartlesville chapter of COPD affiliated with the
Congress of Racial Equality (CORE), becoming the only chapter of CORE below the
Mason–Dixon line. The group recruited an African-American doctor to live and work in the black community of Bartlesville. They, together with the
YWCA, sponsored interracial conferences and seminars. In 1939, only 99 of the 774 Southern public libraries provided services for African American patrons. In the Bartlesville Public Library, Brown had been providing service to African Americans since the 1920s. By 1950, the library subscribed to
Ebony and
Negro Digest. Brown was also interested in integrating the children's storytime but was dissuaded from doing so by the library commission. She then turned her attention to an educational exhibit on "Negro Culture from Africa to Today". Brown upset some in the community when she took two female African-American teachers to a local diner in downtown Bartlesville. The diner refused to serve them and Brown and her companions staged a
sit-in. She took African-American friends with her to church and promoted a lecture by
Bayard Rustin, an African-American Quaker pacifist. The leaders of the community then began to work to remove Brown. On July 10, the city commission dismissed the entire library board. A new board was immediately appointed which supported the city's position regarding Brown. Brown was interviewed by the city commission on July 25, 1950. She refused to answer questions about her private life except in writing at her attorney's request. When asked about the subversive materials in the library, she responded that they were three of seventy-five publications to which she subscribed. She continued that she did not feel she should censor what the public chose to read and that she had subscribed to them for over 15 years. In spite of no clear evidence of subversion, she was fired the same day. ==Personal life==
