MGM issued a number of EP "albums" with two or three EPs in individual "pages" or sleeves within the fold-open "albums." Typically, the individual EPs had different individual numbers. This discography is a numerical cross reference to the individual EP numbers included within two or three EP sets. The EP set number is given after the title and artist. In the discography below, X4001/2, for example, means that X4001 is "The Bandwagon" Part 1, and X4002 is "The Bandwagon" Part 2, both included in the 2-EP "album" released as EP X207.

The X4000 series of individual EP numbers allows dates to be assigned to the EPs that were issued after X207, but which had catalog numbers before X207. Most of these were issued in 1953, but some were issued as late as 1955.

This information comes partly from our record collections, but in the main from the listing in The MGM Labels: A Discography by Michel Ruppli and Ed Novitsky (Greenwood Press, 1998), which has a wealth of additional information on MGM sessions, as well as information on the individual tracks on each EP.
