This question can only be answered by consulting a number of different sources, each of which has its own approach to compiling information. So be prepared for different counts and rankings!

Here is a list of the most current and reliable sources for this kind of information. When the source is Web-based, a link has been provided; contact your nearest library branch concerning the availability of paper-based info sources.

• Missouri Manufacturers Register (Manufacturers' News) 2006
• Springfield Area Chamber of Commerce, Top 40+ Employers Web Page
• Springfield Business Journal's 2006 Book of Lists

The Library recommends that you use these lists only as the beginning of your research into the area economy or of your job search. Further (and often more in-depth) informational resources are likely to exist concerning any or all of these employers, as well as many other employers having fewer employees than the arbitrary limits that these lists have chosen to impose. We would appreciate hearing about any other lists that you would consider relevant for these purposes.
