1. On Durkheim and the sociology of knowledge, see Kurt H. Wolff, “Anomie and the Sociology of Knowledge, in Durkheim and Today,” in Survival and Sociology ,
pp.83—96.
2. The most important contributions centered on Karl Mannheim, especially (but not exclusively) his Ideologie und Utopie (1929). They are collected in Volker Meja and Nico Stehr, eds. and introd. , Der Streit urn die Wissenssoziologie (Frankfurt: Suhrkamp, 1982), 2 vols.; for a selection in English, see Meja and Stehr, eds. and introd., Knowledge and Politics: The Sociology of Knowledge Dispute (London and New York: Routledge, 1990).
3. Aside from the very useful preface by one of its two translators, Louis Wirth, the English version also contains an introduction written by Mannheim for the occasion and an encyclopedia article on the sociology of knowledge published originally in 1931, i.e., two years after Ideologie und Utopie. See Mannheim, Ideology and Utopia, trans. Louis Wirth and Edward Shils (New York: Harcourt, Brace, 1936).
4. See Mannheim's 1946 letter, reprinted in Kurt H. Wolff, Beyond the Sociology of Knowledge: An Introduction and a Development (Lanham, London , New York: University Press of America , 1983), pp. 202—204. This letter was written a few months before his death.
