Jackie Robinson broke baseball's color barrier fifty years ago, but that was not his only contribution to the civil rights struggle in America. To illustrate Robinson's continuing activism in the civil rights struggle, the National Archives and Records Administration (NARA) has recently made available (as part of its Teaching with Documents series) a new site that includes nine documents (letters and telegrams, in .gif format) in the correspondence between Robinson and four US presidents. The annotated correspondence shows Robinson's steadfastness in pursuing civil rights, and some of his prescient opinions about what might happen if civil rights continued to be denied to African Americans.
