Presents summary data on solar thermal collector shipments for the years 1974 through 1993 and summary data on photovoltaic cells and module shipments for the years 1982 through 1993. Detailed information for solar thermal collectors and photovoltaic cells and modules is presented for 1993. Charts and tables.

Solar Collectors, Energy Storage, and Materials covers the materials and basic components needed for solar thermal energy systems. Using thermal performance and durability as the major criteria, the twenty six chapters emphasize the modeling and assessment of devices rather than their application or cost. Each part begins with an overview and concludes with an assessment of current issues and opportunities. The contributors have been careful to document failures as well as successes in materials research. This is the fifth volume in a series that distills the results of the intensive research on and development of solar thermal energy conversion technologies from 1975 to 1986. Francis de Winter is President of the Altas Corporation, Santa Cruz, California and a member of the Santa Cruz Energy Advisory Committee. Contents: Solar Collectors. Collector Concepts and Designs.

In more than nine decades of Girl Scouting, a vast popular and material culture has given rise to a wealth of Girl Scout history collections. More than an identification guide to uniforms, insignia, and other Girl Scout objects, this work also documents when changes occurred and why new items were introduced. Placing these objects in context, this essential guide provides a discerning look at the history and development of the Girl Scout Movement in the United States. Scholars and aficionados of Girl Scout history, costume history, women's studies, popular culture, and dress will welcome this indispensable and definitive resource. This new, expanded edition, with hundreds of illustrations, photographs, and tables, is indisputably the go-to source for information on all Girl Scout uniforms, insignia, awards, and handbooks, as well as dolls, postcards, posters, calendars, and more--from the founding of the Girl Scouts in 1912 through the present day. "An invaluable resource to Girl Scout councils managing a history collection. And, beyond that . . . an informative and intriguing glimpse . . . into the evolution of a Movement that . . . today is the world's preeminent organization dedicated solely to girls." --Cynthia B. Thompson, chair, National Board of Directors, and Kathy Cloninger, national chief executive officer, GSUSA "An indispensable reference for collectors; a fascinating resource for anyone interested in Girl Scouting, this comprehensive guide to Girl Scout memorabilia is firmly grounded in the history of the Girl Scouts of the United States. Mary Degenhardt and Judith Kirsch show us what Girl Scouts wore and read, and explain how changes in uniforms, insignia, and publications reflect the evolution of Girl Scout programs and the expansion of opportunities for American girls. Reading this book is like walking through a fine museum where material culture brings the past to life." --Anastatia Sims, author of Negotiating Boundaries of Southern Womanhood
