A great many trade associations, professional societies, unions, industrial organizations, and government agencies provide career information that is valuable to counselors and jobseekers. For the convenience of Career Guide users, some of these organizations and their Internet addresses, are listed at the end of each industry statement. Although these references were carefully compiled, the Bureau of Labor Statistics has neither authority nor facilities for investigating the organizations or the information or publications that may be sent in response to a request and cannot guarantee the accuracy of such information. The listing of an organization, therefore, does not constitute in any way an endorsement or recommendation by the Bureau either of the organization and its activities or of the information it may supply. Each organization has sole responsibility for whatever information it may issue.

The industry information contained in the Career Guide presents a general, composite description of firms and jobs and cannot be expected to reflect work situations in specific establishments or localities. The Career Guide, therefore, is not intended and should not be used as a guide for determining wages, hours, the right of a particular union to represent workers, appropriate bargaining units, or formal job evaluation systems. Nor should earnings data in the Career Guide be used to compute future loss of earnings in adjudication proceedings involving work injuries or accidental deaths.
