This collection records stories and recollections associated with the history of science, technology, and medicine. Divided into groups by discipline, the Virtual Center is a directory of nearly 3,500 websites that deal with the history of science. The Practical Guide is a useful section that guides visitors through the process of planning, designing, and building a history-themed website. The Memory Bank allows visitors to share and read thoughts or recollection about any of ECHO's ongoing projects. Remembering the Moon Walk, for example, contains 130 responses from individuals who remember the event. Also included are collections featuring Women in Science and Engineering, Three Mile Island, and The Washington Metro. By registering, visitors can create their own memory bank using ECHO's tools for historians. The site would be an appropriate starting place for students researching a history of science topic.

Presents 108 sound recordings produced in the mid- to late 1890s by pioneer recording manufacturer and inventor Emile Berliner (1851-1929) as well as more than 400 additional items from the inventor's papers. Berliner, based in Washington, D.C., developed the microphone, the gramophone player, and the flat recording disc. The recordings on the site—each averaging about two minutes in length and available in Real Audio, MP3, and WAV formats—include Western music (band and orchestra, instrumentalists, popular music vocalists and vocal groups, classical and opera, and foreign language songs), spoken word selections (comedy, speeches, addresses), and a variety of ghost songs and dances of Native American peoples recorded by ethnologist James Mooney. Selections include Buffalo Bill Cody's "Sentiments on the Cuban Question," recorded in April 1898; John Philip Sousa's band; humorist Cal Stewart relating one of his popular "Uncle Josh" stories; and Victor Herbert's 22nd Regiment Band.

Most of the other items—articles, books, catalogs, clippings, correspondence, diaries, lectures, notes, pamphlets, patents, photographs, scrapbooks, and speeches—are from the 1870s to the early 1930s. Also includes a 23-title bibliography, links to eight related sites, a timeline, a family tree, and three informative essays (2,000-4,000 words) on Berliner's life, the history of the gramophone, and the Library's collection of Berliner recordings. A valuable site for those studying the beginnings of the recording industry, turn-of-the-century popular culture, and the milieu of American inventors in the period from the 1870s to the Great Depression.

More than 55,000 color images of tobacco advertisements from litigated cases, dating back to 1909, are now available on this site, created as a stipulation of the Master Settlement Agreement between the tobacco industry and various states' attorneys general. In addition, more than 26 million pages of documents concerning "research, manufacturing, marketing, advertising and sales of cigarettes, among other topics" are provided in linked sites to the four tobacco companies involved—Philip Morris, R. J. Reynolds, Lorillard, and Brown and Williamson—and to two industry organizations, the Tobacco Institute and the Council for Tobacco Research. Ads and documents can be accessed by date, brand name, title words, and persons mentioned, among other searchable fields. Images can be magnified and rotated. An important site for those studying the historical uses of advertising to promote smoking and those with a more general interest in some of the motifs in ad texts and images that have become part of 20th-century American life.
