For anyone researching any aspect of radio history or radio's impact on the daily lives of four generations of Americans from the 1920s-1960s, this first-ever guide to 3,800 primary and secondary sources focuses on radio history and radio's contribution to America's cultural heritage from the 1920s-1960s. Includes 2,300 Special Collections in public and private repositories throughout the United States, a Bibliography with 1,400 citations grouped into 54 user friendly categories from Advertising to World War II, 100+ research oriented Internet sites and an Index that integrates all 3,800 listings and which can be searched by program title, person or subject. Listing of collections is especially valuable as it pulls together...a host of potentially valuable resources, annotating each one carefully. - Communication Booknotes Quarterly, Spring 2006 An amazing achievement to have located all that material and put it into a form so easy to use. - Fuller French, The Broadcast ARTS Library The real pleasure of this book lies in discovering the wealth of material scattered around the country in smaller facilities. - Chuck Howell, Curator, Library of American Broadcasting, College Park, MD This guide is a wonderful new resource for anyone interested in research on Old Time Radio. - Jeanette M. Berard, Curator, American Radio Archives, Thousand Oaks Public Library
