Since 2005, a philanthropic organization, PJ Books, has set out to influence American Jews by reaching them in one of their most tender, intimate family moments: parents reading to children. The program uses children's books to influence Jewish families' values and practices. This chapter argues that PJ Library demonstrates the burden that American Jewish institutions place on popular culture to shape their communities. Though staff members deny that PJ Library is engaged in religious activity, the organization does, in fact, use children's books as a tool to shape American Jewish religion. It uses children's books to introduce families to or reinforce their connection with sacred rituals and Jewish customs. More broadly, PJ Library seeks to persuade American Jewish families to make Judaism an important part of their lives and to connect them, one illustrated book at a time, to networks that will help them do so.
