Tad Lathrop's most recent book, the college text "Discover Jazz," coedited with Smithsonian Curator of American Music John Edward Hasse, explores jazz evolution through the written contributions of distinguished scholars from across the musical and cultural spectrum, hundreds of photographs and images, a set of CDs with listening guides, and online documentaries, filmed performances, streaming audio, and study guides.

Tad's book on the music business, "This Business of Music Marketing and Promotion," draws from his work in music publishing, licensing, journalism, producing, marketing, and education with such companies as Broadcast Music Inc. (BMI), Cherry Lane Music (publisher of Quincy Jones, Metallica, John Mayer); Holt Music; Billboard (directing their line of music and entertainment books); and MTV. The book's contributors include the former director of publicity for the Atlanta Symphony Orchestra and publicist for the Allman Brothers and ZZ Top; the Vice President, Marketing and Sales, of EMI-Capitol Entertainment; and the founder of the blues label Alligator Records; among many other corporate and indie music makers. Tad expanded one of that book's chapters, on marketing and promoting music in foreign countries, to the full-length volume "This Business of Global Music Marketing," published in 2007.
