The C19 is the "forum for announcements and business related to" The Society of Nineteenth-Century Americanists. According to their website, they are "the first academic organization dedicated to nineteenth-century American literary and cultural studies... Our C19 Circuit events, short regional events and workshops — in the spirit of the nineteenth-century lyceum circuit — are focused on bringing together students, teachers, and scholars to discuss topics related to nineteenth-century America. C19 Cluster Groups further enable those with special interests to develop institutional and intellectual connections."
This website gives access to their Academic Journal (J19), their conference (CFP), and their podcast.
