The conditions faced by African Americans in St. Louis County is well-documented in the January 1970 Hearings of the United States Commission on Civil Rights (USCCR). A full transcript of the 1970 Hearings is available via the Hathi Trust. The evidence and testimony collected there also features in the USCCR's 1974 report Equal Opportunity in Suburbia (also available from Hathi).
The events in Ferguson are the subject now of a number of films, including Whose Streets? and Jane Gillooly's ethereal documentary, Where the Pavement Ends.
