“Poring over documents in the National Archives, I discovered that immigration authorities had been after my relatives from the very beginning, but never really caught on to what they were doing. I received help from numerous libraries, historical societies, and academicians. I nagged relatives, friends, and customers to rummage through their attics, basements, and closets for photographs, papers, and other memorabilia from fairs, art shows, and family rites. I looked at films and videotapes, scrapbooks and letters, packing slips and tax records” (OGM, page xx).
