The Occupational Outlook Handbook at http://www.bls.gov/ooh/ is a publication of the United States Department of Labor's Bureau of Labor Statistics that includes information about the nature of work, working conditions, training and education, earnings and job outlook for hundreds of different occupations in the United States. It is released biennially with a companion publication, the Career Guide to Industries and is available free of charge from the Bureau of Labor Statistics' website.
The Occupational Outlook Handbook (OOH) at http://www.bls.gov/ooh/ provides information on what workers do; the work environment; education, training, and other qualifications; pay; the job outlook; information on state and area data; similar occupations; and sources of additional information, for 329 occupational profiles covering about 83 percent of the jobs in the economy.
The OOH is broken up into clusters of similar occupations. In order to find an occupation, browse the occupation groups of interest on the left-hand side of the homepage, or use the A–Z Index if you know the specific occupation. You may search for occupations by using the selector drop-down menus on the OOH homepage. Select by pay range, entry-level education, on-the-job training, projected number of new jobs, or projected growth rate. If you know the specific occupation you are interested in, you may enter a job title into the “Search Handbook” box on the top right-hand side of the homepage. In addition, you may browse by clicking any of the three links titled “highest paying,” “fastest growing (projected),” and “most new jobs (projected).”
