The Ad*Access Project presents images and database information for over 7,000 advertisements printed in U.S. and Canadian newspapers and magazines between 1911 and 1955. Ad*Access concentrates on five main subject areas: Radio, Television, Transportation, Beauty and Hygiene, and World War II, providing a coherent view of a number of major campaigns and companies through images preserved in one particular advertising collection available at Duke University.
The collection consists of 4,500 photographs documenting natural environments, ecologies, and plant communities in the United States at the end of the nineteenth and the beginning of the twentieth century. Produced between 1891 and 1936, these photographs provide an overview of important representative natural landscapes across the nation. They demonstrate the character of a wide range of American topography, its forestation, aridity, shifting coastal dune complexes, and watercourses. Among the natural features these images document are ecological settings such as dunes, bogs, forests, and deserts; individual plants from the Ponderosa pine and birch to grasses and mosses; landscape features like the Grand Canyon, Lake Superior, and the Sierra Nevada; and the consequences of natural and human changes to the environment ranging from erosion and floods to irrigation and lumbering.

A militarily plausible nuclear attack, even "limited," could be expected to kill people and to inflict economic damage on a scale unprecedented in American experience; a large-scale nuclear exchange would be a calamity unprecedented in human history. This collection of documents includes: "The Atomic Bombings of Hiroshima and Nagasaki" by The Manhattan Engineer District (1946), "The Effects of Nuclear War, Worldwide Effects of Nuclear War" by U.S. Arms Control and Disarmament Agency, and "The Effects of Nuclear Weapons" by Samuel Glasstone and Philip J.

At the height of McCarthyism, Oppenheimer's politics during the 1930s came under scrutiny and ultimately led to his undoing at the hands of the Atomic Energy Commission in 1953. He asked for a security hearing to review the charges, which went on for four weeks and heard testimony from 40 witnesses including Oppenheimer. Documents include: ?Testimony in the Matter of J. Robert Oppenheimer - Gen. Leslie Groves, Hans Bethe, George F. Kerman, I. I. Rabi, Edward Teller,? and ?Decision and Opinions of the United States Atomic Energy Commission in the Matter of Dr. J. Robert Oppenheimer.?
Weddell seals have a large repertoire of very strange vocalizations–everything from chugs, chirps, trills, and whistles to what sounds like something from outer space. Weddells make these sounds both underwater and on top of the sea ice. Our soundtrack composer Steve Perez used hydrophone recordings the project obtained under NMFS Permit 1032-1917 to interweave with guitar and midi to create an other-worldly composition consisting of some of those Weddell seal vocalizations recorded by the Weddell Population Ecology project. Video field footage obtained by project members Eric Boyd and Terrill Paterson under NMFS Permit 17236. Video editing and production by Mary Lynn Price. Learn more at WeddellSealScience.com!

Historic Pittsburgh, an extensive digital resource created at the University of Pittsburgh, offers both an entry point and substantive classroom resources for teachers of American History at various grade and university levels. This Web site enables access to historic material held by the University of Pittsburgh's University Library System, the Library & Archives at the Heinz History Center, Carnegie Museum of Art, Chatham College Archives, Pittsburgh History & Landmarks Foundation, and Point Park University Archives. The project represents a model of cooperation between libraries, museums and institutions of higher learning in providing centralized access to selections of their respective historic materials.The books allows teachers to focus on historical currents, social movements and individual historical personalities, both famous and less well-known. Thousands of photographs offer students at all levels opportunities for observation, comparison and inference.
