Scope and ContentDVD - Microsoft Word document with information on almost 5,000 shipwrecks on the Great Lakes, 1679-2001. This 2011 DVD, release 24.5, contains the following header: “This document is the most complete and accurate list of losses of Great Lakes commercial vessels in existence, but it may be considered to be a work in progress, since my research continues. It includes commercial vessels which were total losses or were declared total losses and oater recovered, plus a few wrecks which were significant for other reasons (e.g. loss of life), but were later recovered. I am happy to share this with any and all interested parties, but as of Apr, 2000, it represents about 13 years of steady work, so if you use any of the materials herein, PLEASE CREDIT to David D. Swayze, Lake Isabella, MI.”
