Photos of Xiao Fang, a photojournalist who was a contemporary of Sha Fei, are published in John Spencer's In Serach of Modern China. I also found that Wu Yinxian's photos are in Magnum's archive.

There're some interesting exhibitions of photojournalists recently. One is Weegee (Arthur Fellig) http://www.nytimes.com/2006/06/09/arts/design/09weeg.html, now on display at the Intenational Center of Photography. He worked for tabolid papers, shooting sensational, provocative, and eye-catching scenes at New York City during its turbulent years in the 30s, 40s and 50s.

Another exhibition is a war photographer, Dogulas Duncan, now on view at the HRC, Univeristy of Texas at Austin. The HRC is holds one of the richest resources of photography and photographic archieves in the country. Duncan sereved as a marine during the Korean War, and the millitaray experience was documented by the marine/photographer. This is War comprises of pictures he took during the war.
