Created by the Learning Technology Center at the University of Texas at Austin’s College of Education (with support from the National Endowment for the Humanities), the Presidential Timeline of the 20th Century provides a single point of access to an ever-growing selection of digitized assets from the collections of the 12 Presidential Libraries of the National Archives. Among these assets, you’ll find documents, photographs, audio recordings, and video relating to events in the presidents’ lives, and a multimedia exhibit featuring the key challenges and decisions each faced–including the stock market crash, Pearl Harbor, Hiroshima, Little Rock school integration, Gulf of Tonkin, Berlin Wall, and more. A special section for educators suggests activities that incorporate the site’s various resources; for example, a webquest on the Gulf of Tonkin Resolution asks students to research the topic and answer the question, “As an editor of one of the most important and influential newspapers in the country, would you have supported the decision?”
