Discography is the study and listing of sound recordings.
This word stems from:
1. the gramophone record, often called a "disc", the dominant commercial medium of sound recording for most of the 20th century
A listing of all recordings which a musician or singer features on can be called their "discography". Additionally, discographies may be compiled based on a particular musical genre or record label, etc.
The term "discography" was popularized in the 1930s by collectors of jazz records. Jazz fans did research and self published discographies about when jazz records were made and what musicians were on the records, as record companies did not commonly include that information on/with the records at that time.
