The International Socialist Review was a monthly magazine published in Chicago, Illinois by Charles H. Kerr & Co. from 1900 until 1918. The magazine was chiefly a Marxist theoretical journal during its first years under the editorship of A.M. Simons. Beginning in 1908 the publication took a turn to the left with publisher Charles H. Kerr taking over the main editorial task. The later Review featured heavy use of photographic illustration on glossy paper and mixed news of the contemporary labor movement with its typical theoretical fare.

The Charles H. Kerr Publishing Company is an American publishing company. The company was established in Chicago, Illinois, in 1886 as Charles H. Kerr & Co. by Charles Hope Kerr, originally to promote his Unitarian views. As Kerr's personal interests moved from religion to populism to Marxism and he became interested in the labor movement, the company's publications took a similar turn. During the 1920s Kerr ceded control of the firm to the Proletarian Party of America, which continued the imprint as its official publishing house throughout its four decades of organized existence.
