摘要：A professional journalist before developing his brilliant career as a North American sociologist, Robert Ezra Park always put journalism at the center of his work as a researcher. He wrote two books about it: Crowd and Public, based on his doctoral dissertation presented in Germany, in 1903, and translated to English only in 1972, and The Immigrant Press and its Problems, published in 1921, besides dozens of articles that appeared in specialized magazines. His wide-ranging work published during his career as a university professor offers several fundamental contributions to the journalism study. In this article I focus on two of them: his definition of journalism as a form of knowledge and his suggestion to study journalism as a social institution.
