As project manager, together with Brigitte Halbmayr, she supervised the "Mauthausen Eyewitness Project", in which around 800 interviews were conducted with survivors of the Mauthausen concentration camp in a total of 23 countries under the scientific direction of the historian Gerhard Botz from the Ludwig Boltzmann Institute for Historical Social Science in Vienna.
The volume 'Mauthausen revisited', co-edited by Amesberger, shows how school pupils capture their impressions of the memorial site in photographs.
Female Experiences in Nazi Concentration Camps" (2004), Helga Amesberger and her colleagues Katrin Auer and Brigitte Halbmayr created a standard work on a topic that has received little attention.
The research project she carried out together with Brigitte Halbmayr and Kerstin Lercher on the "Registration of the names of formerly imprisoned Austrians in Ravensbrück concentration camp" was completed in 2009.
In addition to various academic studies (see Publications), Amesberger has published numerous articles in specialist journals and collective works on the subject of the National Socialist persecution of women.
