The Anton Webern Gesamtausgabe (AWG) is a critical-historical edition which aims to make Webern’s entire oeuvre accessible to musical scholarship and practice in a scholarly form. The edition includes not only all the works Webern himself had forwarded to be printed but also their unpublished variants. It also includes compositions that were never made public in his lifetime, works from his youth and student years, as well as fragments, sketches, arrangements and revisions of his and other scores.

The AWG is based at the Department of Musicology of the University of Basel and works in close collaboration with the Paul Sacher Stiftung (Basel), which holds most of Webern's existing source material. Since October 2006 the Swiss National Scientific Foundation, and since 2019 the Swiss Academy of Humanities and Social Sciences has supported its activities. Furthermore, since 2008 an office has been set up in Vienna in cooperation with the Österreichische Akademie der Wissenschaften. Its aim is to find new information and undisclosed documents concerning the history, the reception, and the historical context of Webern’s oeuvre. This collaboration has been extended thanks to a grant from the Ernst von Siemens Musikstiftung.

The AWG will be released in a Hybrid Print-Online Edition, the printed volumes being published by Universal Edition (Vienna), the online accessible components and datasets being presented as Open Data via a separate Web application (https://edition.anton-webern.ch) and processed via the DaSCH Service Platform (DSP) of the Swiss National Data & Service Center for the Humanities (DaSCH). In addition, the DaSCH will make the data accessible and store it for the long term.

The AWG understands itself as a centre of competence comprising, beside its editorial work, a network of archival, documentary, analytical, communication, service-providing, and organizational activities.
