These are directories which cover the Pittsburgh area or the state of Pennsylvania. In many cases they will be more inclusive than the resources listed in the company profiles section, and thus are particularly useful in finding information on small local companies. If you are researching a local public company, refer to the Sources for Corporate Financial Data page for the best resources.

If you are viewing this page from outside the Pittsburgh area, check with your local library. Many of these items have equivalents for other cities and states.
