Inspired by the process of creating a library for his fifteenth-century home near the Loire, in France, Alberto Manguel, the acclaimed writer on books and reading, has taken up the subject of libraries. “Libraries,” he says, “have always seemed to me pleasantly mad places, and for as long as I can remember I’ve been seduced by their labyrinthine logic.” In this personal, deliberately unsystematic, and wide-ranging book, he offers a captivating meditation on the meaning of libraries.
