Mark had 18 collections of her work published, most notably Streetwise and Ward 81. Her work was exhibited at galleries and museums worldwide and widely published in Life, Rolling Stone, The New Yorker, New York Times, and Vanity Fair. She was a member of Magnum Photos between 1977 and 1981. She received numerous accolades, including three Robert F. Kennedy Journalism Awards, three fellowships from the National Endowment for the Arts, the 2014 Lifetime Achievement in Photography Award from the George Eastman House and the Outstanding Contribution Photography Award from the World Photography Organisation.
