With over 20,000 individual contributors and over 150,000 digital objects ranging from stories and email to photographs and video, this is one of the largest collections of materials on the tragic events of September 11, 2001, online or off. In 2003, it became one of the first digital collections to be acquired by the Library of Congress.
For the fourth anniversary of the attacks, I produced an interactive map of views of Ground Zero by integrating the collection with Google’s mapping program.

Both a precursor and parallel to the September 11 Digital Archive, the Echo Project uses electronic media to capture the history of science, technology, and medicine. The site includes a comprehensive catalog of other history of science Web sites, a guide to using the internet as a vehicle for history, and a place for scientists, engineers, doctors, and the general public to record their memories of important scientific events and movements.

The Hurricane Digital Memory Bank is a new project modeled on the September 11 Digital Archive, with a similar mission to capture the digital record of the present for future researchers before it is lost. This site reaches out to the millions of people affected by the terrible hurricanes of 2005, including Katrina, Rita, and Wilma. A major innovation of this site is that it situates these recollections, images, and other digital files on a browsable map so that viewers can see patterns based on geography, demographics, and other factors.
