The public is invited to contribute to “Our Marathon,” a crowd-sourced, digital archive of pictures, videos, stories and social media related to the Boston Marathon bombing. Northeastern University, which hosts the project, stresses that no contribution is too small. According to its website, the archive will “allow the public to explore not only what happened during the event, but also how the event was experienced by Bostonians, visitors to the city, and those many members of the ‘Boston diaspora’ who were far away but deeply engaged in the unfolding events. The archive will serve as a long-term memorial, preserving these records for students and researchers, providing future historians with invaluable, local windows into an important national event.” Library staff will provide laptop stations and assist residents in uploading their stories (or photos, text messages, social media, etc.) to the archive’s website.
