Letters and Other Texts is the third and final volume of the posthumous texts of Gilles Deleuze, collected for publication in French on the twentieth anniversary of his death. It contains several letters addressed to his contemporaries (Michel Foucault, Pierre Klossowski, François Châtelet, and Clément Rosset, among others). Of particular importance are the letters addressed to Félix Guattari, which offer an irreplaceable account of their work as a duo from Anti-Oedipus to What is Philosophy? Later letters provide a new perspective on Deleuze's work as he responds to students' questions.

his volume also offers a set of unpublished or hard-to-find texts, including some essays from Deleuze's youth, a few unusual drawings, and a long interview from 1973 on Anti-Oedipus with Guattari.
