You can make a list of all manufacturing companies you are interested in and search for their website on the web.\n\nOr you can go to Thomas Register's ThomasNet http://www.thomasnet.com/ as they lists all the manufacturing companies in North America for each industrial sector. For international manufacturing companies, go to Thomas Global http://www.thomasglobal.com/ . Each listing provides a description of the company and the contact information.

There are books in the Reference Section of public libraries that list U.S. companies (maybe world) by type (i.e., pharmaceutical) giving their names, addresses, phone numbers, and other pertinent information about them.  Ask the librarian for assistance.  (I used to use them; sorry I can't think of the titles.)
