I am a longtime collector of Salem's "Industrial Era"( 1870 - 1970) history. Among the items in my collection are; books, photos, postcards, stereo-views, catalogs, etc. I have massive amounts of material on / about Salem railroads, trolleys, Coast Guard Air Station , commercial & manufacturing ( inc. tanning & shoes ) retailing, people & groups. harbor related marine activities, etc. I am actively working on gathering rare material om the Great Salem Fire of 1914. I've been collecting ( photos, postcards, reports, period magazine & newspaper articles, etc. ) all manor of material about the fire for almost 40 years.
See my latest book, "Salem in Stereo, Victorian Salem in 3-D"; a collection of 70 Salem stereo-views, spiral bound,with a viewer. Available from the publisher, http://www.hardyhouse.us/home.htm
