Book excerpt: As the telecommunication and information field expands and becomes more varied, so do publications about these technologies and industries. This book is a first attempt to provide a general guide to that wealth of English-language publications -- both books and periodicals -- on all aspects of telecommunication. It is a comprehensive, evaluative sourcebook for telecommunications research in the United States that brings together a topically-arranged, cross-referenced, and indexed volume in one place. The information provided is only available by consulting a succession of different directories, guides, bibliographies, yearbooks, and other resources. On the one hand, it is a directory that describes in detail the major entities that comprise the American telecommunication research infrastructure including federal and state government offices and agencies, and private, public, and corporate research institutions. On the other hand, it is a bibliography that identifies and assesses the most important and useful reference and critical resources about U.S. telecommunication history, technology, industry and economics, social applications and impacts, plus policy, law and regulations, and role in the global telecommunication marketplace. No existing guide covers all of these aspects in the depth and detail of this volume.
