Volume 3 of the historico-critical edition completes J.G. Droysen’s (1808-1884) ›Historik‹ (Outline of the Principles of History). The last three cycles of lectures can be reconstructed as a self-contained entity, unlike other earlier texts. The first volume in the set consists basically of the reconstruction of the texts of the lectures held in 1882/83 and 1879 as well as an outline of the ›Historik‹ (primarily the 1882 version, with reference to all the other available texts). The second volume contains textual variants, annotations, a two-part editorial report (including an account of the ›Historik‹ in the context of Droysen’s teaching and publishing activities) as well as a detailed concordance of the manuscript transmissions and an index for all the volumes of this edition.
