'Ex Libris' recounts a lifelong love affair with books and language. For Fadiman, as for many passionate readers, the books she loves have become chapters in her own life story. Writing with remarkable grace, she revives the tradition of the well-crafted personal essay, moving easily from anecdotes about Coleridge and Orwell to tales of her own pathologically literary family. As someone who played at blocks with her father's twenty-two-volume set of Trollope ("My Ancestral Castles") and who considered herself truly married only when she and her husband had merged collections ("Marrying Libraries"), she is exquisitely well equipped to expand upon the art of flyleaf inscriptions, the perverse pleasures of compulsive proofreading, the allure of long words, and the satisfactions of reading aloud.
