This site offers two exhibits featuring the photography of Camilo Jose Vergara that document decay and renewal in the "post-industrial" cities of Camden, NJ, and Richmond, CA, since the 1970s. The collection of more than 450 photographs explores the transformation of these cities' urban landscapes through the erosion of their "late 19th and early 20th-century architectural grandeur" through "their subsequent neglect and abandonment" to "scattered efforts at renewal." The site has an essay by Vergara that explains his work and introduces the two collections. The Camden exhibit has a large collection of photographs, organized into 24 themed galleries, and an introductory essay by Howard Gillette placing the photographs in a historical context. The Richmond exhibit is somewhat smaller, with 10 themed galleries.

The collection of photographs can be browsed by theme or by using the site's interactive city maps. Some of the themes are geographic; some are tours surveying an area of the city. Other themes group images sharing similar characteristics such as post-industrial, churches, and people. Additionally, some of the images are linked to views of the subject at different periods to show change over time. The site also has a feature allowing visitors to post comments on the photographs. This site is of interest to anyone researching urban history in the 20th century or these two cities specifically.

This website is devoted to the life, work, and memory of John F. Kennedy, the 35th president of the U.S. Of primary interest to historians and teachers are the "Historical Resources and Education" and "Public Programs" sections of the website, which shed light on important events in early 1960s political history, including the Cuban missile crisis, the Vietnam War, the civil rights movement, the Peace Corps, the space program, and the 1963 Nuclear Test Ban Treaty. Users unfamiliar with the history of the Kennedy White House might begin with the "Timeline," which puts events important to the Kennedy administration in a larger political and cultural context, or "Biographies and Profiles," which presents a Kennedy family tree and profiles of early 1960s notables such as Fidel Castro, Robert McNamara, and Arthur M. Schlesinger, Jr. "White House Diary" further familiarizes users with Kennedy's day-to-day activities as President.

The website also includes hundreds of historical sources including speeches, photographs, telegrams, correspondence, eulogies for Bobby Kennedy, JFK, and Jacqueline Kennedy Onassis (all accessible through an Advanced Search feature), and transcripts of more than 170 oral interviews with notables such as John Kenneth Galbraith (Harvard University economic professor and Ambassador to India), Supreme Court Justice Felix Frankfurter, singer Harry Belafonte, and President Gerald Ford. In some cases, the original audio files of speeches are also included. Several lesson plans designed for elementary, middle, and high school students use materials from this archive to address topics such as Kennedy's inaugural address, the Cuban missile crisis, and the civil rights movement.

This well-designed website, companion to the PBS documentary, offers a wide variety of secondary material on the Carter presidency. "People and Places" offers short profiles of Carter, his wife Rosalynn, his brother Billy, Carter's White House staff (collectively known as "The Georgia Mafia"), Speaker of the House Thomas P. "Tip" O_Neill, and Vice-President Walter Mondale.

It also offers short essays on key events of Carter's presidency, including the election of 1976, the Egyptian-Israeli peace talks at Camp David, the Iranian hostage crisis, Carter's July 1979 "Crisis of Confidence" speech, and the election of 1980. Many of the essays link to special features, such as the extensive media coverage of the Iranian hostage crisis and the text of the "Crisis of Confidence" speech. "Teacher's Guide" offers nine suggestions for classroom learning activities in four categories: economics, civics, history, and geography. The site also includes a detailed chronology of Carter's life and a small photo gallery with 16 images. This site provides a useful overview of Carter's life and the political and diplomatic history of his presidency.

In February 1971 to July 1973, President Richard Nixon secretly began recording phone conversations and meetings, compiling thousands of hours of tape. Created in 2007 by a Texas A&M University history professor, this website intends to provide "the most complete digitized Nixon tape collection in existence."

At present, only a fraction of the recordings are available. Visitors may listen to MP3 versions of over 500 conversations organized by primary conversation participant; 29 conversations organized by topic themes; and more than 2,000 hours of conversations organized by the date of their release to the general public.

Though the site promises that all recordings will eventually be accompanied by full transcripts, accompanying material is spotty. Some recordings are accompanied by corresponding entries from the presidential daily diary, some by general outlines of the recording's topics, and a handful by full transcripts. The recordings vary in quality, from fully audible to inaudibly faint or noise-obscured.

The website is not searchable (the search engine on the home page searches the web at large). As it stands, it may be useful to educators as a casual introduction to the recordings for students, but locating specific content (to accompany lesson plans or complement events being taught in class) would require significant time.
