Traced

What happened to the ancient Egyptians? The Persians? The Romans? The Mayans? ARE WE THEIR DESCENDANTS? Recent genetic discoveries are uncovering surprising links between us and the peoples of old—links that rewrite race, ethnicity, and human history. Today’s Native Americans descend from Central Asians who arrived in the early A.D. era. Abraham, Isaac, and Jacob still have clearly identifiable descendants, albeit rare ones. Every people group on earth can genetically trace their origins to Noah and his three sons.

The theory of traces employs techniques and tackles problems from quite diverse areas which include formal language theory, combinatorics, graph theory, algebra, logic, and the theory of concurrent systems. In all these areas the theory of traces has led to interesting problems and significant results. It has made an especially big impact in formal language theory and the theory of concurrent systems. In both these disciplines it is a well-recognized and dynamic research area. Within formal language theory it yields the theory of partially commutative monoids, and provides an important connection between languages and graphs. Within the theory of concurrent systems it provides an important formal framework for the analysis and synthesis of concurrent systems.This monograph covers all important research lines of the theory of traces; each chapter is devoted to one research line and is written by leading experts. The book is organized in such a way that each chapter can be read independently ? and hence it is very suitable for advanced courses or seminars on formal language theory, the theory of concurrent systems, the theory of semigroups, and combinatorics. An extensive bibliography is included. At present, there is no other book of this type on trace theory.

In most college and university libraries, materials published before 1800 have been moved into special collections, while the post-1923 books remain in general circulation. But books published between these dates are vulnerable to deaccessioning, as libraries increasingly reconfigure access to public-domain texts via digital repositories such as Google Books. Even libraries with strong commitments to their print collections are clearing out the duplicates, assuming that circulating copies of any given nineteenth-century edition are essentially identical to one another. When you look closely, however, you see that they are not. Many nineteenth-century books were donated by alumni or their families decades ago, and many of them bear traces left behind by the people who first owned and used them. In Book Traces, Andrew M. Stauffer adopts what he calls "guided serendipity" as a tactic in pursuit of two goals: first, to read nineteenth-century poetry through the clues and objects earlier readers left in their books and, second, to defend the value of keeping the physical volumes on the shelves. Finding in such books of poetry the inscriptions, annotations, and insertions made by their original owners, and using them as exemplary case studies, Stauffer shows how the physical, historical book enables a modern reader to encounter poetry through the eyes of someone for whom it was personal.

With a New Preface by the Author Through personal journeys and historical inquiry, this PEN Literary Award finalist explores how America’s still unfolding history and ideas of “race” have marked its people and the land. Sand and stone are Earth’s fragmented memory. Each of us, too, is a landscape inscribed by memory and loss. One life–defining lesson Lauret Savoy learned as a young girl was this: the American land did not hate. As an educator and Earth historian, she has tracked the continent’s past from the relics of deep time; but the paths of ancestors toward her—paths of free and enslaved Africans, colonists from Europe, and peoples indigenous to this land—lie largely eroded and lost. A provocative and powerful mosaic that ranges across a continent and across time, from twisted terrain within the San Andreas Fault zone to a South Carolina plantation, from national parks to burial grounds, from “Indian Territory” and the U.S.–Mexico Border to the U.S. capital, Trace grapples with a searing national history to reveal the often unvoiced presence of the past. In distinctive and illuminating prose that is attentive to the rhythms of language and landscapes, she weaves together human stories of migration, silence, and displacement, as epic as the continent they survey, with uplifted mountains, braided streams, and eroded canyons. Gifted with this manifold vision, and graced by a scientific and lyrical diligence, she delves through fragmented histories—natural, personal, cultural—to find shadowy outlines of other stories of place in America. "Every landscape is an accumulation," reads one epigraph. "Life must be lived amidst that which was made before." Courageously and masterfully, Lauret Savoy does so in this beautiful book: she lives there, making sense of this land and its troubled past, reconciling what it means to inhabit terrains of memory—and to be one.

A Mexican road novel of love, hate, drugs, and the Mexican Revolution. The Trace is a masterful, poetic novel about a journey through Mexico taken by a couple recovering from a world shattered. Driving through the Chihuahua Desert, they retrace the route of nineteenth-century American writer Ambrose Bierce (who disappeared during the Mexican Revolution) and try to piece together their lives after a devastating incident involving their adolescent son. With tenderness and precision, Gander explores the intimacies of their relationship as they travel through Mexican towns, through picturesque canyons and desertcapes, on a journey through the the heart of the Mexican landscape. Taking a shortcut through the brutally hot desert home, their car overheats miles from nowhere, the novel spinning out of control, with devastating consequences. . . . Poet Forrest Gander’s first novel As a Friend was acclaimed as “profound and relentlessly beautiful (Rikki Ducornet). With The Trace, Gander has accomplished another brilliant work, containing unforgettable poetic descriptions of Mexico and a story both violent and tender.
