There’s a long tradition of writers writing about their libraries. Some of the first modern essays—by Michel de Montaigne and Sir Francis Bacon—are on that very subject. Among more recent publications, you might enjoy Anne Fadiman’s collection Ex Libris or Larry McMurtry’s Walter Benjamin at the Dairy Queen. The trouble with people writing about their libraries is, well, every writer has one. It’s like writing about your left hand. Or your M.F.A. program. But McMurtry is a special case. If he had never written Lonesome Dove or The Last Picture Show, he would be famous—at least among collectors—as one of the country’s most respected dealers in used and rare books. When he writes about his library, he always has something interesting to say.
