Ya know, I have a source for info that never even crossed my mind to post here for the forum. I have not gotten a new one in some time but was trying to find a company for something yesterday. Some of you may know of this book: Thomas Regional Directory, I have a hard cover book that's over 1200 pages but I'm not sure how they do it now, it's probably just on the net now. My book is from 2001, yea I know, they used to make books back then. I put in the old web address and got redirected here: http://www.thomasnet.com/
It's by region and it's all manufacturing supply related, so if you want to know who is making what in your region like chemicals, I would look into it. In this book for my region (Greater Michigan) there are about 300 listings just under the headings Chemical and Chemicals.
