The history of reading looks "beyond the codex, beyond the margins, into a swirling global history, still unfolding, of how we communicate." The work of Archie L. Dick, a professor of information science at the University of Pretoria, is just one example. Dick's new book, "The Hidden History of South Africa's Book and Reading Cultures," uncovers evidence of a robust reading culture among the non-elites of South Africa.
