I apologize for the silence in this venue. My idle interneting time has been otherwise occupied lately with digesting various sources from the Bentley and elsewhere into Arborwiki pages on (mostly Ypsilanti) past local industries.

Check out the Arborwiki Industrial History Project for a fledgling entry point, or pages like Ferrier Machine Works (now the Ypsi food co-op), Louis Z. Foerster (prominent German-Canadian Ypsilanti brewer), or Federal Screw Works (vacant and likely doomed plant in Chelsea) as example pages.

None of these are "finished" products, as if anything on a wiki ever is, but it seems to be a topic that I've managed to get a few other people interested in working on, so it will hopefully grow.
