The William Fulton Papers (1993-1996) contains Fulton's research files used in writing his book, The Reluctant Metropolis: the Politics of Urban Growth in Los Angeles.

The majority of newspaper clippings are from the Las Vegas Review-Journal and the Las Vegas Sun. The materials also include reports on economic and housing development in Southern Nevada as well as drafts of the book's Chapter 12, "Cloning Los Angeles" which discusses the growth of Las Vegas throughout the 1980s and 1990s.
