and extend the older series Volksliedstudien (Folk Song Studies). In 2010, the Deutsches Musicalarchiv (German Musical Archive) was founded, focused on the musical genre, as a legally dependent unit of the Archive, to provide a research basis, and supported by a circle of friends and sponsors. An additional Internationales Popmusikarchiv (International Pop Music Archive) is planned. In 2011, the Deutsche Forschungsgemeinschaft awarded the institute the title of a "herausragende Forschungsbibliothek" (outstanding research library), and provided financial support for the establishment of the pop music archive. In 2012, the research institute moved into new premises with an area of 1,000 square metres (previously only 400 square metres were available in the former Meiers residential building) and new equipment in Rosastraße in Freiburg. Recently, these rooms have been supplemented by a separate external storage building. Until 2014, the Archive was formally an "authority of the country subordinate to the Ministry of Science, Research and Art". In March 2014, the Ministry of Science decided to integrate the Archive into the University of Freiburg, named Zentrum für Populäre Kultur und Musik, as a research centre for popular culture and music in past and presence.

The centre also houses a number of special collections, for example on , on industrial folk music and on individual song media (song pamphlets, handwritten and printed songbooks.
