Ronald E. Day. Indexing It All: The Subject in the Age of Documentation, Information, and Data. Cambridge, The MIT Press, 2014.

A critical history of the modern tradition of documentation, tracing the representation of individuals and groups in the form of documents, information, and data. In this book, Ronald Day offers a critical history of the modern tradition of documentation. Focusing on the documentary index (understood as a mode of social positioning), and drawing on the work of the French documentalist Suzanne Briet, Day explores the understanding and uses of indexicality. He examines the transition as indexes went from being explicit professional structures that mediated users and documents to being implicit infrastructural devices used in everyday information and communication acts. Doing so, he also traces three epistemic eras in the representation of individuals and groups, first in the forms of documents, then information, then data.
