An industry is a group of businesses that provide a particular product or service. An Industry Overview can help you identify major companies, developing trends, market share/size, operation concerns, government regulations, and consumer behaviors.
Industry Classification Codes are used in many of the library's online resources to identify industries. The two most common industry classification codes are SIC codes and NAICS codes.
For more information about these codes, see the explanatory page on the NAICS website.
