"The Story of PCUN and the Farmworker Movement in Oregon", oauthored by U. of O. Professor Lynn Stephen, was originally published in 2011. It was the first history of PCUN ever published.
The revised 2012 edition, published by the UO's Center for Latino/a and Latin American Studies, is a 57-page online publication that highlights the history of PCUN (Pineros y Campesinos Unidos del Noroeste, or Northwest Treeplanters and Farmworkers United) within the context of Oregon and U.S. history. The Oregon farmworker movement began with the U.S. Bracero Program in the 1940s, and led to settled Mexican communities in Willamette Valley towns including Woodburn, St. Paul, Independence and Gervais.
