Both an expert and a collector, James Geary has devoted his life to aphorisms-and the last few years to organizing, indexing, and even translating them. The result is Geary's Guide, featuring aphorists like Voltaire, Twain, Shakespeare, Nietzsche, Woody Allen, Muhammad Ali, Emily Dickinson, and Mae West, as well as international practitioners appearing in English for the first time. But it is more than just a conventional anthology. It is also an encyclopedia, containing brief biographies of each author in addition to a selection of his or her aphorisms. The book is a field guide, too, with aphorists organized into eight different "species," such as Comics, Critics & Satirists; Icons & Iconoclasts; and Painters & Poets. The book's two indexes-by author and by subject-make it easily searchable, while its unique organizational structure and Geary's lively biographical entries set it apart from all previous reference works. A perfect follow-up to Geary's New York Times bestseller The World in a Phrase, Geary's Guide is eminently suitable for browsing or for sustained reading. A comprehensive guide to our most intimate, idiosyncratic literary form, the book is an indispensable tool for writers and public speakers as well as essential reading for all language lovers.

Earth's near-surface mineralogy has diversified over more than 4.5 b.y. from no more than a dozen preplanetary refractory mineral species (what have been referred to as "ur-minerals" by Hazen et al., 2008) to around 5,000 species (based on the list of minerals approved by the International Mineralogical Association; http://rruff.info/ima). This dramatic diversification is a consequence of three principal physical, chemical, and biological processes: element selection and concentration (primarily through planetary differentiation and fluidrock interactions); an expanded range of mineral-forming environments (including temperature, pressure, redox, and activities of volatile species); and the influence of the biosphere.

The Oxford Handbook of Byzantine Studies presents discussions by leading experts on all significant aspects of this diverse and fast-growing field. Byzantine Studies deals with the history and culture of the Byzantine Empire, the eastern half of the Late Roman Empire, from the fourth to the fourteenth century. Its centre was the city formerly known as Byzantium, refounded as Constantinople in 324 CE, the present-day Istanbul. Under its emperors, patriarchs, and all-pervasive bureaucracy Byzantium developed a distinctive society: Greek in language, Roman in legal system, and Christian in religion. Byzantium's impact in the European Middle Ages is hard to over-estimate, as a bulwark against invaders, as a meeting-point for trade from Asia and the Mediterranean, as a guardian of the classical literary and artistic heritage, and as a creator of its own magnificent artistic style.
