Subseries 3.4 includes copies of wartime documents such as government notices and preparation instructions for incarceration, loyalty questionnaires, “evacuation” data, and lists of people held at the particular incarceration camps where the U.S. government sent most Japanese Americans from Oregon, as well as a few editorial pieces of the time, arguing both for and against forced removal. The research of Homer Yasui and others in this subseries offers insight on the incarceration and wartime experiences of individuals, as well as the Oregon Nikkei experience overall.
