The Oxford Project is a book capturing the stories of 100 Oxford residents, along with photographs of them taken 20 years apart. Photographer Peter Feldstein (himself an Oxford resident) took photographs of all but three of his neighbors during 1984. In 2005 and 2006, he returned with writer Stephen G. Bloom to take updated photos and interview as many of those original residents as possible.[11][12]
