The Catalogue (German language edition: Der Katalog) is a boxed set comprising eight albums by Kraftwerk that were released from 1974 to 2003. All albums are digitally remastered, with most of the cover art redesigned, including rare photographs in the liner notes that were not part of each album's original release.Due to licensing issues, three of these albums—Computer World, Electric Cafe (now re-christened with its original working title of Techno Pop) and The Mix—are unavailable in the U.S.
