If you follow this link you can access all 9 issues of the Zeitschrift für Sozialforschung, a seminal German magazine that published essays by Theodor W. Adorno, Raymond Aron, Walter Benjamin, Erich Fromm, Maurice Halbwachs, Max Horkheimer, Alexandre Koyré, Leo Löwenthal, Richard Löwenthal, Herbert Marcuse, Margaret Mead and many others. And if that is not enough for you, this link sends you to a place where you can download the collected works of Walter Benjamin. The Zeitschrift für Sozialforschung, founded by the great Max Horkheimer, is the magazine of the Institute for Social Research, and appeared between 1932 (first issue) and 1941 (last issue). The publication history of the Zeitschrift reflects the turbulent European history of its time. While the first issue was published in Germany, issues 2-7 were published in Paris and the two last issues were published in New York, re-titled Studies in Philosophy and Social Science. If you can read German, get all of it, but if you can’t, read the two last volumes. This is seriously, seriously awesome. I will admit that I have a bit of a stiffy for Horkheimer, Adorno, and occasionally Löwenthal and Marcuse, but really. You can’t not read this. Adorno was one of last century’s most brilliant minds (and a deeply humbling and stunning writer of prose) and the other writers here not far behind. Now go and read!
