Geology of Illinois has been compiled from more than a century of earth science investigations in Illinois. For the first time, this information has been summarized and made accessible in one volume to help both geologists and non-geologists better understand how the state's mostly unseen geology affects, and is affected by, life on the surface. More than 200 color photographs, maps, and drawings illustrate the text. Topics include : the history of geological investigations in Illinois; the impact of the state's tectonic and structural history; the properties and classification of its rocks and sediments; the rich heritage of its land, water, and mineral resources; the threats from its geological hazards; and the application of geological information to societal issues.

Commences with detailed accounts of nitrogen cycles and nitrate production in atmospheric, terrestrial and aquatic systems. Using a geographical perspective and stressing the fundamental importance of the drainage basin as the primary unit for water quality control, the second section deals with nitrate transport patterns. Lastly, it considers various strategies for nitrate pollution including legislative, land use and water treatment options.

Located in Penobscot Bay, Vinalhaven Island is a land mass about 10 by 5 miles, with the town situated on Carvers' Harbor, 15 miles from the mainland. Always a working community, Vinalhaven presently serves as one of the largest lobstering centers in the world. Islanders, summer residents, visitors, and other interested persons on the mainland and elsewhere are invited to partake of this striking photographic record of the island as it was between 1860 and 1960. Contained within are classic views that bring to life the island's ongoing fishing and granite industries. Some show the enormous columns for the Cathedral of St. John the Divine in New York City being cut and polished; others document the carving of the eagles for the Buffalo, NY, Post Office. Lesser-known occupations are portrayed as well, like the making of horse nets, which employed many women. Readers are given the rare opportunity to meet such people as granite company operator Moses Webster; Joseph Bodwell (a Maine governor); Edward Russell (from Ireland) and Joseph Black (from Scotland); and O.P. Lyons, founder of the first local newspaper and band.

This established text is the only introduction to qualitative research methodologies in the field of library and information management. Its extensive coverage encompasses all aspects of qualitative research work from conception to completion, and all types of study in a variety of settings from multi-site projects to data organization. The book features many case studies and examples, and offers a comprehensive manual of practice designed for LIS professionals. This new edition has been thoroughly revised and includes three new chapters. It has been updated to take account of the substantial growth in the amount and quality of web-based information relevant to qualitative research methods and practice, and the many developments in software applications and resources. The authors have identified a clear need for a new chapter on the evaluation of existing research, as a gateway into new research for information professionals. The final chapter, 'Human Resources In Knowledge Management', takes the form of a model case study, and is an 'ideal' qualitative investigation in an information setting. It exemplifies many of the approaches to qualitative research discussed in earlier chapters. Readership: Directed primarily at the beginner researcher, this book also offers a practical refresher in this important area for the more experienced researcher. It is a useful tool for all practitioners and researchers in information organizations, whether libraries, archives, knowledge management centres, record management centres, or any other type of information service provider.

This book discusses the karst and pseudokarst of the Upper Midwest, USA, consisting of the states of Minnesota, Wisconsin, Iowa, and Illinois—the first regional synthesis in 40 years. Starting with an overview of the regional geology of what is largely glaciated fluviokarst and paleokarst developed on Paleozoic carbonates, but including other lithologies such as the St. Peter Sandstone and the Ft. Dodge Gypsum, the caves, springs, sinkholes, and karst hydrogeology of each state are described. Special attention is devoted to the region’s longest caves: Coldwater Cave, Mystery Cave, and the Minnesota Cave Preserve caves. Application of tools such as data loggers and LiDAR, with new conceptual models such as hypogenic speleogenesis, has been transformative here. Special topics include lead and zinc mining in the Driftless Area, vertebrate and invertebrate cave fauna near the Laurentide ice limit, the impact and policies of nutrient and herbicide intensive modern agriculture on karst, and paleoclimate studies. The discovery, exploration, institutional history of caving organizations, and show caves of the Upper Midwest, from the year 1700 onwards, are brought up to date. The top 10 historical paradigms of cave and karst science in the Midwest are reviewed. Perspectives on paleontology, archeology, and Native American rock art are included.
