The history of the book is everywhere, so widely diffused that it merits comparison with the famously elusive Scarlet Pimpernel, whose pursuers sought him without success. Like that figure, book history passes among us in disguise, reluctant to reveal its presence even as it gains ever-greater recognition. In some quarters, it lurks within the domain of bibliography, a field of scholarship dedicated to describing the histories of printed texts and, in the service of this enterprise, concerned with the details of book-making. Elsewhere, book history installs itself within descriptions of libraries and education, sharing, with the first of these, a concern for how old books were accumulated and classified and, with the second, for the many ramifications of literacy and the fashioning of schoolbooks. Together with the history of journalism it studies how news was disseminated and ponders the significance of periodicals, be these newspapers or magazines. Political history has been another convenient site of disguise in the wake of efforts to connect the public sphere and concepts of nation with the emergence of print culture. And, of course, book history has enjoyed a long and fruitful kinship with literary history, a relationship freshly energized in recent decades as literary historians turned to describing the rise and remaking of a canon and to emphasizing the mediations that all texts undergo—the “sociology of texts,” to borrow a phrase made famous by D. F. McKenzie. To this list we can add the version of intellectual history that reconstructs the reading of a person or group and employs this data to generalize about the coming of the Enlightenment and similar formations.
