One year after the opening of the visitor centre, the technology and content of the research stations "Wer ist Wer?" (Who's who?) have been updated. The two stations "Wer ist Wer 1" (with data prior to 1918) and "Wer ist Wer 2" (with data from 1918 to the present day) were merged. As a result, all the information can now be viewed on all three available stations at the same time. The search function was revised as well and now permits combined queries according to several criteria such as person, federal province and political party.
