This anthology was published in conjunction with two exhibitions that took place at the Neues Museum Weserburg, Bremen and at the Museum d’Art Contemporani, Barcelona. They were mainly devoted to the subject of records and record covers and complemented by works on audio-cassettes as well as by some unreleased or rare works on compact disc.

The editor has chosen to publish a discography, not in alphabetical order, as it usually the case, but in chronological order. This approach highlight the often-surprising dates of creation of some of the works. An index, at the end of the publication, enables the reader to situate the works of art and their creators in context. A glossary enlights the historical or technical aspects of the works or their supports. The principal purpose of this publication is to constitute a discography as exhaustive as possible.
