The Flusser-Quellen was originally conceived as the first volume of Andreas Müller-Pohle’s Flusser Editions, which should have been published by European Photography in 1996/1997. Klaus Sanders continued working on the text until 2002. The final revised edition, with a new foreword by Daniel Irrgang, has now finally been made accessible on-line by the Vilém Flusser Archive in Berlin.
