Volume 4.2 of Michael Müllers catalogue raisonné is devoted exclusively to the large-format, 126-part work Lektüre und Ablenkung (2016/17), which belongs to the group of works known as indexes. The basis for the index presented in this volume is Jacques Derridas book Vom Geist. But far more than the content of that publication, Müller is interested in the inevitable distractions that arise during the intense reading of a book. Meticulously documented, elaborated and developed in a variety of media - from text notes to drawings and photographs to mathematical notations - the distractions integrated into the work unfold a complex web of references, categorisations and relationships that uncover structures of the digressive mind.
