He followed that in 2010 with "The Typewriter Is Holy: The Complete, Uncensored History of the Beat Generation" (New York, NY: Free Press, 2010). Morgan has also authored or edited a half-dozen other works relating to the Beats, including collections of Ginsberg's essays ("Deliberate Prose: Selected Essays, 1952–1995," New York: HarperCollins, 2000), of the poet's last poems ("Death & Fame: Poems, 1993-1997"; coedited with Bob Rosenthal and Peter Hale, New York: HarperFlamingo, 1999), and of Gregory Corso's correspondence ("An Accidental Autobiography: The Selected Letters of Gregory Corso," New York: New Directions, 2003). Through City Lights in San Francisco, he has published two guides, "" (1997) and "" (2003). The latter appeared during the fiftieth anniversary celebration of City Lights, to which Morgan also contributed with a series of free walking tours of the North Beach section of San Francisco, once a center of bohemian life in the city and home for many of the Beats in the 1950s and 1960s. In the course of his decades of research on the Beats, Morgan gathered perhaps the largest private collections of printed works by and about Ferlinghetti and Ginsberg in private hands. He found it increasingly difficult to maintain these two very large and valuable collections in his New York apartment, and reluctantly decided to part with them. Knowing that Ferlinghetti was a UNC-Chapel Hill alumnus, he decided in the fall of 2001 to offer his collection of the San Francisco poet to the University of North Carolina at Chapel Hill libraries. Discussions with library officials led to the transfer of the collection to Chapel Hill in December of that year, partly as sale and partly as gift. Pleased with the outcome, Morgan then offered a similar arrangement for his even more extensive Allen Ginsberg collection. The materials were delivered to the Rare Book Collection in Wilson Library in August 2002.
