Allgemeine Encyclopädie der Wissenschaften und Künste
The Allgemeine Encyclopädie der Wissenschaften und Künste ("Universal Encyclopaedia of Sciences and Arts") was a 19th-century German encyclopaedia published by Johann Samuel Ersch and Johann Gottfried Gruber, therefore also known as the "Ersch-Gruber." One of the most ambitious encyclopaedia projects ever, it remains uncompleted. It was designed and begun in 1813 by Professor Ersch to satisfy the wants of Germans, only in part supplied by foreign works. It was stopped by the Napoleonic Wars until 1816, when Professor Gottlieb Hufeland joined, but he died on November 25, 1817, while the specimen part  was at press. The first volume appeared in Leipzig in 1818. The editors of the different sections at various times were some of the best-known men of learning in Germany, including Gruber, M.H.E. Meier, Hermann Brockhaus, W. Müller and A.G. Hoffmann of Jena. Naturalist Eduard Poeppig wrote most of the articles on the Americas. All articles bear the authors' names, and those not ready in time were placed at the end of their letter. The work is divided into three sections: From its beginning through 1830, the "Encyclopädie" was published at Leipzig by Johan Friedrich Gleditsch. From 1831 until  publication ceased in 1889, the "Encyclopädie" was published by Friedrich Arnold Brockhaus, also of Leipzig. Gleditsch published volumes 1 through 21 of the first section; volumes 1 through 7 of the second, but only the first volume of the third section. Brockhaus published the remaining volumes through 1889. By 1889, when the project was abandoned, the "Encyclopädie" had reached 167 volumes. The article about Greece alone covered 3,668 pages, spanning eight volumes.
