As an academic, Jacobs focuses on American film.[1] She has written four books: The Wages of Sin (1991) on the evolution of fallen women cinema due to Hollywood censorship;[6] Theatre to Cinema (1997; co-authored with Ben Brewster), on the relationship between stage visual effects and their early film counterparts;[7] The Decline of Sentiment (2008), on the change of values in 1920s American film;[8] and Film Rhythm After Sound (2015), on the history of film technology during the transition between silent film and sound.[9] Her next book, John Ford at Work, examines the career of John Ford in relation to evolving film technology, will be released in October 2025.[10]
In 2002,[11] she was awarded a Guggenheim Fellowship for "a study of the decline of sentiment in American silent film."[2] In addition to film history, she has also taught animation history at UW Madison.[1]
