Der Esperantist was, from 1965 to 1990, the official newsletter of the East GermanEsperanto movement. After organizing the Esperantomovement in the former East Germany, under the aegis of the quasi-governmental Cultural Association , the new Centra Laborrondo de Esperanto-Amikoj began publishing the bilingual Der Esperantist in the A5 format. Over the years the Esperanto-language content increased, and the number of German articlesdeclined. The newsletter was edited by a committee, but the chiefeditors were Eugen Menger and Detlev Blanke. Including a German-language special edition for the 1987 centennial of Esperanto, 165 issues were published with a total of 3,728 pages over the entireprint run. Issue 163 of Der Esperantist contained a cumulative index of articles. The print run was generally 4,000 to 5,000 copies, half of which were mailed to subscribers in East Germany. The remainder of the copies were shipped in bulk to other countries which had no local Esperanto publications, as well as to the Soviet Union, where there was interest in the newsletter. Numerous copies were also sent in free exchange for Esperanto publications from other countries. The newsletter was typographically modest and frequently was delayed in publication, but the collected copies of Der Esperantist are now important for the historiography of the GDREA, particularly as the published articles have now been indexed in depth in two slim volumes:
Linde Knöschke and Ino Kolbe: der esperantist 1 - 164. Register. Teil I. , Gesellschaft für Interlinguistik e. V., Berlin, 1997, 120 pp.
Ino Kolbe: der esperantist 1 - 164. Register Teil II. , Arbeitsgruppe Geschichte des Esperanto-Verbandes der DDR, Berlin, 1998, 120 pp.
An essay on Der Esperantist can also be found in Torsten Bendias's "El la vivo de GDR: der esperantist " in Simone Barck, Martina Langermann and Siegfried Lokatis, Zwischen 'Mosaik' und 'Einheit': Zeitschriften in der DDR. Ch. LinksVerlag, Berlin, 1999, pp. 202 – 213.
