ABSTRACT
AT ABOUT THE TIME that investigations of chaos were becoming fairly common, the well-established journal Physica, which had already acquired some of the aspects of three separate journals, inaugurated a fourth series, Physica D, to be devoted to nonlinear phenomena. This move took place a few years after the founding of another journal, Nonlinear Analysis: Theory, Methods and Applications. Several years later volume 1, number 1 of Nonlinearity appeared. Contributors to these journals represented many disciplines, and came from many institutions, including the Center for Nonlinear Studies at the Los Alamos National Laboratories, the Center for Nonlinear Dynamics at the University of Texas, and the Institute for Nonlinear Science at the University of California. What did their contributions deal with? In many instances it was chaos.
