The Gullah people are one of our most distinctive cultural groups. Isolated off the South Carolina-Georgia coast for nearly three centuries, the native black population of the Sea Islands has developed a vibrant way of life that remains, in many ways, as African as it is American. This landmark volume tells a multifaceted story of this venerable society, emphasizing its roots in Africa, its unique imprint on America, and current threats to its survival. With a keen sense of the limits to establishing origins and tracing adaptations, William S. Pollitzer discusses such aspects of Gullah history and culture as language, religion, family and social relationships, music, folklore, trades and skills, and arts and crafts. Readers will learn of the indigo- and rice-growing skills that slaves taught to their masters, the echoes of an African past that are woven into baskets and stitched into quilts, the forms and phrasings that identify Gullah speech, and much more. Pollitzer also presents a wealth of data on blood composition, bone structure, disease, and other biological factors. This research not only underscores ongoing health challenges to the Gullah people but also helps to highlight their complex ties to various African peoples. Drawing on fields from archaeology and anthropology to linguistics and medicine, The Gullah People and Their African Heritage celebrates a remarkable people and calls on us to help protect their irreplaceable culture.

Winner of the 2012 Award for Excellence presented by the Greater Hudson Heritage Network The seemingly unremarkable Hudson River town of New Baltimore has had its ups and downs, you could certainly say that. Here, generations of families have worked the fields until the yield tapped out, built and repaired ships and barges until the steam age died, and harvested ice until refrigeration made "icebox" a quaint colloquialism. Yet despite the various economic, social, and military forces that have transformed the town, New Baltimore and its residents have endured, celebrating their triumphs and enduring their tragedies. Drawing on original town board minutes, Greene County surrogate and land records, federal and state military records, land patents, colonial documents, conversations with local residents, censuses, and period newspapers, town historian Clesson S. Bush provides an authentic portrait of a small-town community, making the routine—and drama—of small-town life on the Hudson River come alive.

A counterpoint to biodiversity, geodiversity describes the rocks, sediments, soils, fossils, landforms, and the physical processes that underlie our environment. The first book to focus exclusively on the subject, Geodiversity describes the interrelationships between geodiversity and biodiversity, the value of geodiversity to society, as well as current threats to its existence. Illustrated with global case studies throughout, the book examines traditional approaches to protecting biodiversity and the new management agenda which is starting to be used instead.
