The correspondence of 1785 was influenced mainly by Jacobi's publication of the »Spinozabriefe« (Spinoza Letters). During this year he corresponded primarily with Johann Georg Hamann, as well as the young theologian Thomas Wizenmann, Princess Gallitzin, Goethe, Herder, Gleim, Forster, Lavater, Kleuker and Soemmerring. More than one quarter of the letters of 1875 had not been published up to now; this includes just under 90 letters. The volume contains an appendix which includes 138 previously unknown letters written between 1764 and 1784 (either handed down or made available), among which is the previously unpublished correspondence with F. K. v. Hompesch (temporarily responsible for finances as a minister of Karl Theodor's), which document Jacobi's political activities in Munich, among other things. The volume concludes with a detailed index of persons.
