It is a department of the University of Oxford and is governed by a group of 15 academics appointed by the Vice-Chancellor known as the Delegates of the Press.
Two fully-bound print editions of the OED have been published under its current name, in 1928 and 1989. , the editors had completed the third edition up to Hh.

It is for German what the Oxford English Dictionary is for English, containing detailed historical information about the origin and use over time of German words, with examples taken from actual documents.
