約80年ぶりに発見され2002年にフランスで刊行された自筆草稿を遂に英訳。『一般言語学講義』理解に修正を迫る。英訳版は、序文、ソシュール自身の講義ノート、ソシュール書誌（1970-2004年）含む。This manuscript is published now in English for the first time in an edition edited by Simon Bouquet and Rudolf Engler, and translated and introduced by Carol Sanders and Matthew Pires, all leading Saussure scholars. The book includes an earlier discovered manuscript on the philosophy of language, Saussure's own notes for lectures, and a comprehensive bibliography of major work on Saussure from 1970 to 2004. It is remarkable that for eighty years the understanding of Saussure's thought has depended on an incomplete and non-definitive text, the sometimes aphoristic formulations of which gave rise to many creative interpretations and arguments for and against Saussure.
