In 1975, he moved to Los Angeles, becoming resident film historian of the Academy of Motion Picture Arts and Sciences, responsible for most of its educational and cultural activities.
Slide published his first book, Early American Cinema, in 1970 (it was subsequently revised and rewritten in 1994), and since then has been a prolific writer on little known areas of entertainment history.
The sequel volume, The International Film Industry: A Historical Dictionary (1989) was named outstanding academic book of the year by Choice magazine.
His work as a writer and editor led Charles Champlin of the Los Angeles Times in to describe Slide as “a one-man publishing phenomenon".
