When “Six Cultures” appeared as part of the MLA Reports of Surveys and Studies in the Teaching of Modern Foreign Languages in 1961, we planned to make periodic revisions and we here publish revised and updated versions of the lists in four languages. Readers interested in French and Luso-Brazilian cultures may consult the original lists in the Appendix to the MLA Selective List of Materials (New York: MLA, 1962. $1.00) or they may obtain a reprint of the “Six Cultures” article by sending 50 cents to the MLA Materials Center. We reprint here the general introduction by Lawrence Wylie, Chairman of the original committee.
