This six-volume discography lists full available details (dates, titles, personnel) on all recording sessions made between 1934 and 1973 by the Decca label, as well as its subsidiary labels, Brunswick, Coral, and Vocalion. Material from other sources (Brunswick recordings of the 1920s and the Signature label, for example) reissued by Decca are covered. Included in the discography are details on most of the big bands of the pre-war era (Count Basie, Fletcher Henderson, Jimmy Dorsey, Woody Herman, Jimmy Lunceford, Chick Webb) as well as such jazz stars as Louis Armstrong and Art Tatum and such singers as Ella Fitzgerald and Peggy Lee. In addition, Guy Lombardo's dance band, great pop stars like Bing Crosby and Judy Garland, and legendary vocal groups like the Andrews Sisters and the Mills Brothers are covered. Country hit makers such as Jimmy Davis and the Sons of the Pioneers are detailed as well.

Each volume contains an index of artists, with the last volume providing numerical listings of issued recordings, including sections on 78/45 rpm singles, 45 rpm extended plays, 33 rpm albums, and compact discs. This Decca set is essential to all collectors and music libraries concentrating on the era, the key artists, and groups of the period.
