In 1964, the publishing house was merged with the larger VEB Bibliographisches Institut (BI), with which it had previously cooperated already, but it retained its legal independence.
Verlag Enzyklopädie was originally intended to export works from nationalized encyclopedic publishers, but this plan failed.
From 1980, this included the Zeitschrift für Anglistik und Amerikanistik (Journal for English and American Studies) and the Zeitschrift für Germanistik (Journal for German Studies).
In 1988, the number of titles published by the 235 employees together with the VEB Bibliographisches Institut was 246, including 121 first editions.
At the end of May 1991 it was sold to BIFAB Mannheim, and on 1 November 1991 it was resold to Langenscheidt.
