“Bebop Jazz: A Catalog”
"The drawing, which also graced the cover of Dial's triple 10" set Bebob Jazz, is known, and generally suspected to be Berman's first published work. This slim catalog is previously unseen to us, but also appears to be issued that same year, as it lists catalog numbers up to 1030, and no recordings which appeared after 1947. Dial would cease recording jazz records in 1948."—https://www.boo-hooray.com/images/upload/boohooray-catalog2.pdf
