The Beihefte zu editio [editio Supplements] appear as a complement to editio, the international journal dealing with questions of editorship, which is published in association with the relevant working groups of Germanists, philosophers and musicologists. While editio has a preference for fundamental and overarching papers covering editorship in as wide a variety of fields as possible, the Supplements deal with specialised questions from the concrete practice of editorship. In each case, the papers focus on one subject, which has normally arisen from a conference.
