How did the atomic age start? It's a very good question and this digital exhibit from the Oregon State Universities Libraries Special Collection offers some wonderful archival material that tells part of this story. The materials here are divided into 17 different sections, including The Manhattan Project, Civil Defense, and Nuclear Engineering. Each of these sections includes various ephemera (such as book covers, signs, and notes) along with a brief narrative essay. Perhaps the most fascinating section here is the Artistic Interpretations of the Atomic Age area. Here visitors can view images from colorful comic books and movie posters, like the one for "The Atomic Kid" starring Mickey Rooney. The site is rounded out by a detailed bibliography, along with a link to the atomic energy collection finding aid.
