As a way to cope during the difficult period after the attacks on the Word Trade Center on September 11, 2001, many people began to revisit their memories of the buildings themselves. With a keen eye towards preserving some of these materials, National Public Radio brought together artists, historians, and other interested parties in order to collect and preserve various audio traces of these impressive structures. Through an impressive browsing feature, visitors can aurally move through the audio clips contained within the archive, such as an interview with a Taiwanese tourist and a voice mail from a concerned fellow fire fighter based in Austin to his fellow firefighters. Visitors can also search all of the materials by theme, such as commute, elevators, witness, work, and concourse. The “For Educators” section is a real gem, as it contains a number of lesson modules that will help teachers use the site to talk about the nature of historical events, memorials, and civic practices.
