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.

The volume contains papers delivered to the 11th International Specialist Conference of the Working Group for Editing Germanic Texts from 22nd to 25th February 2006 in Weimar. The range of topics covered in the volume is extremely broad, so that it is of interest both for Germanists and for musicologists and historians of philosophy. The papers discuss specific problems arising from current editorial projects and models for editions which are at present in a preparatory stage. At the same time, there is a debate around theoretical aspects of the overall subject of the conference, so that altogether the volume provides a reliable orientation to the present state of editorial theory and practice.
