This was in part because of educational themes in the "Addresses", and in part because of his earlier work at Jena University. Fichte lectured on further versions of his "Wissenschaftslehre". Of these, he only published a brief work from 1810, "The Science of Knowledge in its General Outline" ("Die Wissenschaftslehre, in ihrem allgemeinen Umrisse dargestellt"; also translated as "Outline of the Doctrine of Knowledge"). His son published some of these thirty years after his death. Most only became public in the last decades of the twentieth century, in his collected works. This included reworked versions of the "Doctrine of Science" ("Wissenschaftslehre", 1810–1813), "The Science of Rights" ("Das System der Rechtslehre", 1812), and "The Science of Ethics as Based on the Science of Knowledge" ("Das System der Sittenlehre nach den Principien der Wissenschaftslehre", 1812; 1st ed. 1798). The new standard edition of Fichte's works in German, which supersedes all previous editions, is the "Gesamtausgabe" ("Collected Works" or "Complete Edition", commonly abbreviated as "GA"), prepared by the Bavarian Academy of Sciences: "Gesamtausgabe der Bayerischen Akademie der Wissenschaften", 42 volumes, edited by , Hans Gliwitzky, Erich Fuchs and Peter Schneider, Stuttgart-Bad Cannstatt: Frommann-Holzboog, 1962–2012. It is organized into four parts:  Fichte's works are quoted and cited from "GA", followed by a combination of Roman and Arabic numbers, indicating the series and volume, respectively, and the page number(s). Another edition is "Johann Gottlieb Fichtes sämmtliche Werke" (abbrev. "SW"), ed. I. H. Fichte. Berlin: de Gruyter, 1971.
