A question from Yahoo! Answers:

Where can i get information about what companies supply other companies with goods and services?

If you want a list of companies supplying a particular PRODUCT, you need to go no further than the Thomas Register:

If you want a list of key suppliers for a particular COMPANY, you’d have to dig through newspaper clippings, call the company’s investor relations department (if it has one), or buy this data from someone like Revere Data:
