Oregon Historical Society research on Portland's underground lore

The Oregon Historical Society, which houses regional archives and exhibits, documents both the primary records of Portland's waterfront and the later popular accounts of the Shanghai Tunnels. Researchers affiliated with the Society and other local historians have published work questioning the scale and specifics of the shanghaiing narrative, noting limited contemporary documentation for some of the more dramatic claims. This institutional research has helped frame the tunnels as a contested historical topic that is also part of Portland's living folklore. The debate and archival materials are accessible through the Society's collections and publications.
