The Civil Rights Act of 1960 attempted to rectify loopholes in the 1957 Civil Rights Act that had enabled southern states to continue disenfranchising Black voters and, in Texas, Mexican Americans. The legislation called for federal inspection of voter registration polls and introduced penalties for obstructing a person from registering to vote.

The Civil Rights Act of 1960 aimed to close loopholes in its 1957 predecessor that had allowed continued voter disenfranchisement for African Americans and for Mexicans in Texas.

In early 1959, the newly seated Eighty-Sixth Congress had four major civil rights bills under consideration. Eventually consolidated into the 1960 Civil Rights Act, their purpose was to correct the weaknesses in the 1957 law. Mitchell’s papers from 1959 to 1960 show the extent to which congressional resistance to the passage of meaningful civil rights laws contributed to the lunch counter sit-ins in Greensboro, North Carolina, and to subsequent demonstrations. The papers reveal how the repercussions of these events affected the NAACP’s work in Washington and how, despite their dislike of demonstrations, NAACP officials used them to intensify the civil rights struggle.
Among the act’s seven titles were provisions authorizing federal inspection of local voter registration rolls and penalties for anyone attempting to interfere with voters on the basis of race or color. The law extended the powers of the US Commission on Civil Rights and broadened the legal definition of the verb to vote to encompass all elements of the process: registering, casting a ballot, and properly counting that ballot. Ultimately, Mitchell considered the 1960 act unsuccessful because Congress had failed to include key amendments that would have further strengthened the 1957 act. In the House, representatives used parliamentary tactics to stall employment protections, school desegregation, poll-tax elimination, and other meaningful civil rights reforms. The fight would continue.

The Papers of Clarence Mitchell Jr. series is a detailed record of the NAACP leader’s success in bringing the legislative branch together with the judicial and executive branches to provide civil rights protections during the twentieth century.

"“The Papers of Clarence Mitchell Jr. is a primary source and analytical goldmine for scholars of civil rights and labor struggles in the twentieth-century United States…. Well organized, engagingly written, and edited with cogent commentary, these two volumes (III & IV) take us inside Mitchell’s activist office and let us hear his own words.”" - Journal of Southern History
