The end of an era In 1992 Justus Perthes Verlag, the publisher of PGM, was taken over by Ernst Klett Schulbuchverlag in Stuttgart, altogether with 'Justus Perthes Geographische Verlagsanstalt Darmstadt' (1953-1994). Ernst Klett Verlag continued to run the Perthes publishing house until 2016 in Gotha. In 2003 the Perthes archives (185,000 maps, incl. abt. 11,000 sea charts and abt. 4,000 large size school wall maps, 120,000 geographic publications incl. a few thousand atlases, and 800 m of business archives) were bought by the Free State of Thüringen. In 2004, after 149 years of publication, the journal Petermann’s Geographische Mitteilungen ceased to be published. The municipality of Gotha bought in 2010 the former business premises and the accompanying grounds on Justus-Perthes-Strasse 1–9 and Gotthardstrasse 6. Since 2015, the huge Perthes archive is located at Perthesforum in Gotha, one of the most modern archive facilities in Germany, with around 11,000 square meters of total space for multiple users. The investment in what was then "Thuringia's largest cultural project" amounted to more than 18 million euros. built with funding from the EU, the German federal government and the Thuringian state government. The Perthes family villa at Gotthardstrasse nevertheless was demolished in July 2012 for lack of development options. Many of the letters Petermann sent or received have been saved for future study, as also are the drafts he made for many maps, and are kept in the Perthes Collection of the University of Erfurt Gotha Research Library at 'Perthesforum'.
