Every book I work on for the Pennsylvania State University Press is an education for me. I knew nothing about the Colonial Office Visual Instruction Committee before proofreading this 2018 title by Gabrielle Moser. I was fascinated with her study of the Committee’s lantern slide lectures, “an unusual project produced by the British government at the beginning of the twentieth century that combined geography education and photography to teach schoolchildren around the world what it meant to look and to feel like an imperial citizen.” Ideas that the author explores about belonging and difference, diaspora, and economic and racial justice are particularly meaningful for our times.
