ASHP/CML has been at the forefront of history on the web since the mid-1990s, producing a variety of websites where teachers, students, and the general public can discover the past. Our subjects range from revolutionary France to the twenty-first century U.S. and points in between. We’ve developed primary document and oral history archives, teaching tools, and 3-D re-creations that help users explore such places in the past as P. T. Barnum’s American Museum in 1865, New York City’s Chinatown after the September 11th attacks, and Brooklyn College in the 1950s. We continue to develop new web projects that showcase the latest historical thinking, rich archival resources, and the best new digital tools available.
