Insiders on Boards of Directors

Go to the public library and look up business registries.

I'll ask the librarian for Business Registries. Is it organized so that those companies with many company officers on their board are flagged or there is some way to find them?

Not sure but with the Thomas Registry they provide details of their products and services the companies provide and their officers. To get info on the Board of Directors you need to be a shareholder. As an alternative ask the librarian which government department handles such information.
