Book excerpt: We are so accustomed to use digital memories as data storage devices, that we are oblivious to the improbability of such a practice. Habit hides what we habitually use. To understand the worldwide success of archives and card indexing systems that allow to remember more because they allow to forget more than before, the evolution of scholarly practices and the transformation of cognitive habits in the early modern age must be investigated. This volume contains contributions by nearly every distinguished scholar in the field of early modern knowledge management and filing systems, and offers a remarkable synthesis of the present state of scholarship. A final section explores some current issues in record-keeping and note-taking systems, and provides valuable cues for future research.
