The Complete Country Music Discography, 1922-1942 compiles details of all country music recording sessions through 1942 in a single volume. Based on record-company files and session logs as well as the recording archives of the Country Music Foundation, this discography documents every commercial country music recording, including unreleased sides. Each entry lists the musicians playing at every session, instrumentation, dates and locations, songwriting credits, and recording master numbers and release numbers. An introduction explains how to use the book, research methodology, and editorial policy; summary histories of each key record company are also provided, along with a bibliography. The discography will include alphabetical indexes to all song titles and to musicians listed.
