“Useful Knowledge can stand as a model of informed and scrupulous historicism. The breadth of Rauch’s acquaintance with subliterary and paraliterary texts is truly impressive as he clearly lays out what was at stake for nineteenth-century intellectuals and usefully relates their preoccupations with those that concern us now, as we experience another information revolution.”-Harriet Ritvo, author of The Platypus and the Mermaid, and Other Figments of the Classifying Imagination “A welcome addition to humanistic analyses of science-in-culture. Rauch deftly blends science, history, and literature-novels, speculative fiction, encyclopedias-to explore cultural attitudes to the challenges of new knowledge during the Information Age of the early nineteenth century.”-Ann B. Shteir, York University
