The Illinois Journal of Mathematics (IJM) was founded in 1957 by Reinhold Baer, Joseph L. Doob, Abraham Taub, George Whitehead, and Oscar Zariski. The journal is sponsored by the Department of Mathematics at the University of Illinois at Urbana-Champaign. It aims to disseminate at reasonable cost significant new, peer-reviewed results in all active areas of mathematics research. In addition to its regular editions it has published special volumes in honor of distinguished members of its host department including R. Baer, D. Burkholder, J. D’Angelo, J. Doob, P. Griffith, W. Haken, and P. Schupp. The journal’s editorial board, which counts distinguished mathematicians such as J. Bourgain, A. Calderon, S.S. Chern, H. Kesten, and K. Uhlenbeck among its past members, comprises a mix of preeminent mathematicians from within its host department and across the mathematical research establishment.

Beginning in 2019 IJM is published by Duke University Press on behalf of the Department of Mathematics at the University of Illinois at Urbana-Champaign.
