Ferdinand de Saussure is one of the world's most quoted linguists, which is remarkable as he hardly published anything during his lifetime.Jean Starobinski edited and presented material from them in the 1970s[24] and more has been published since then.[25] Some of his manuscripts, including an unfinished essay discovered in 1996, were published in Writings in General Linguistics, but most of the material in it had already been published in Engler's critical edition of the Course, in 1967 and 1974.His lectures about important principles of language description in Geneva between 1907 and 1911 were collected and published by his pupils posthumously in the famous Cours de linguistique generale in 1916.
