In 2012, the University of Pittsburgh Press launched an "Ayn Rand Society Philosophical Studies" series based on the proceedings of the Society. Smith has written several academic books and papers on Rand's ideas, including "Ayn Rand's Normative Ethics: The Virtuous Egoist", a volume on Rand's ethical theory published by Cambridge University Press. Rand's ideas have also been made subjects of study at Clemson and Duke universities. Scholars of English and American literature have largely ignored her work, although attention to her literary work has increased since the 1990s.
