In 1927, responding to the seemingly overpowering claims of advertisers and mass marketers, engineer Frederick Schlink and economist Stuart Chase published Your Money's Worth, which argued for an "extension of the principle of buying goods according to impartial scientific tests rather than according to the fanfare and triumphs of higher salesmanship." Your Money's Worth became an instant best-seller, and the authors organized Consumers' Research, a testing bureau that provided information and published product tests in a new magazine, Consumers' Research Bulletin. The 1929 stock market crash heightened suspicion of consumer capitalism, and the magazine had 42,000 subscribers by 1932. In 1933, Schlink and Arthur Kallet (executive secretary of Consumers' Research) published 100,000,000 Guinea Pigs: Dangers in Everyday Foods, Drugs, and Cosmetics. The book struck a responsive chord in depression-era America--it went through thirteen printings in its first six months and became one of the best-selling books of the decade. The book's first chapter ("The Great American Guinea Pig"), gave a flavor of their vigorous arguments. Less

The exhibition 1492: AN ONGOING VOYAGE describes both pre- and post-contact America, as well as the Mediterranean world at the same time. Compelling questions are raised, such as: Who lived in the Americas before 1492? Who followed in the wake of Columbus? What was the effect of 1492 for Americans throughout the Western Hemisphere? The Library of Congress' Quincentenary exhibition addresses these questions, as well as other related themes, including fifteenth century European navigation, the myths and facts surrounding the figure of Columbus, and the differences and similarities between European and American world views at the time of contact.

Ever wonder what women were doing during the 1800s or what is known as the antebellum period of United States history? Men are well represented in our history books as they were the powerful, educated leaders of our country. Women, on the other hand, rarely had opportunities to tell their stories. Powerful stories of brave women who helped shape the history of the United States are revealed to students through journals, letters, narratives and other primary sources. Synthesizing information from the various sources, students write their impressions of women in the Northeast, Southeast, or the West during the Nineteenth Century. Less
