After twenty years and the publication of more than seventy books and CDs, Mainspring Press closed down production in late 2020. All books and CDs have now sold out, and this site is currently undergoing redevelopment for other purposes.

Selected Mainspring Press titles have been licensed to the University of California–Santa Barbara and are available on their Discography of American Historical Recordings website. Please note that Mainspring Press retains the copyrights and exclusive control of all publication rights in those works.
