Book excerpt: The late eighteenth century witnessed the emergence of the literary family: a collaborative kinship network of family and friends that, by the end of the century, displayed characteristics of a nascent corporation. This book examines different models of collaboration within English literary families during the period 1760-1820. Beginning with the sibling model of Anna Barbauld and John Aikin, and concluding with the intergenerational model presented by the Godwins and the Shelleys, this study traces the conflict and cooperation that developed within and among literary families as they sought to leave their legacies on the English world of letters.
