Wegner is a widely published author and editor on the subjects of military history of
Nazi Germany and the history of
National Socialism. From 2000 to 2005, Wegner was chairman of the German Committee for the History of the Second World War. He is co-editor of the
book series War in History published by
Verlag Ferdinand Schöningh in Germany. He is also one of the authors of the seminal work
Germany and the Second World War from the
Military History Research Office (MGFA) contributing to several volumes of the series. Several of Wegner's books have been published in English, including
The Waffen-SS: Organization, Ideology and Function. According to historian
Timothy Garton Ash, Wegner is "the leading authority on the
Waffen-SS". Although, as Wegner writes in the book introduction, his focus on the Waffen-SS "concentrates more on the pre-war" years and for the war-time history of the organisation he recommends "especially", George Stein's work ''The Waffen-SS: Hitler's Elite Guard at War 1939–1945''. Wegner was the editor of the 1998 collection of essays that appeared in English as
From Peace to War: Germany, Soviet Russia, and the World, 1939–1941 published by
Berghahn Books. The review at
H-Net finds that: On the whole, the thirty-five essays succeed extremely well in meeting the editors' objectives. Not only does the reader get the promised overview of research and scholarly debates, thanks to the international cast of contributors (nine different countries are represented here)--the book also touches on a lot of international scholarship that because of its vast scope and linguistic diversity would be impossible to master for any single individual. ==Works==
