The collection consists of original correspondence, essays, and articles of George Padmore, from the period following his "expulsion" or resignation from the Communist Party up until the end of World War II. The correspondence is chiefly between Padmore and Henry Lee Moon, editor of the New York newspaper the New Amsterdam.

During this period, Padmore began a heated public exchange with the Communist Party, as they both were sending dueling letters to Moon, and to other newspapers for publication. Included is an essay, signed and annotated by Padmore for the Amsterdam News dated February 3, 1934, related to his expulsion from the Party. There are several autograph and typed letters to Moon. In a letter dated July 9, 1934, Padmore writes about his dispute with the Communist Party, and in another dated April 1945 he asks Moon to promote the idea of a Pan African Congress in his newspaper. Bearing the same above date, is an "Open letter to Earl Browder, Secretary of the American Communist Party," justifying Padmore's break with the Party. The editorial titled "Padmore Replies to Harry Heywood's Slanders" is also included. To be found is a letter from Moon to W. E. B. Du Bois, asking him to participate in the Fifth Pan African Congress.

Also included is an autograph letter signed from Mrs. Moon to her husband, sent from Berlin on May 11, 1933, regarding the state of black and white race relations in Nazi Germany. There are several letters and press releases, mostly sent to Moon, defending the Communist Party for expelling Padmore. There is a letter and an article from Cyril Briggs, the African-American writer and communist political activist, to Moon and the Amsterdam News, justifying the Communist Party's decision to expel Padmore, and a copy of an unsigned article "James Ford answers Padmore's Charges."
