Using independent critical and cultural theory journals that cross the Canada/US border as key examples, this book shows how to interpret the original practices of periodicals by tracing editorial diasporas and transitions to electronic publishing. Back Issues explains the role of independent theory journals in the institutional formation of critical theory and cultural studies in Canada and the US by focusing on two seminal publications, Paul Piccone's Telos and Arthur Kroker's Canadian Journal of Political and Social Theory. Editorial transits across the international border figure largely, as do founding conferences, interpersonal flare-ups, and the conviviality of academic communities and pre-gentrified urban bohemias. Both commensurable and incommensurable relationships between journal projects are analysed, and a hitherto unwritten history of critical and cultural theory in Canada is broached.
