Ecology, Pathology, and the Life of Paper.

This essay examines how evolving ideas about nature, life, and disease influenced the preservation and conceptualization of Europe’s documentary culture from 1650 to 1950, focusing on paper and the essay as media. It traces the historical recognition of books as organic entities vulnerable to insect pests and microbial decay, highlighting eighteenth- and nineteenth-century scientific approaches—such as microscopy, entomology, and bacteriology—that informed new conservation practices. The text details efforts by librarians, naturalists, and chemists to diagnose and treat the “pathologies” of books, culminating in twentieth-century institutions like Italy’s Institute of the Pathology of the Book, which applied medical metaphors and scientific methods to restore and protect paper-based cultural heritage. Throughout, the essay situates libraries and archives as ecological systems requiring holistic care, reflecting broader intersections between natural sciences and documentary stewardship.
