The BLS compiles and publishes an amazing amount of useful economic and compensation-related information. Some of the most popular BLS products include the Consumer Price Index (which we usually call "inflation") and the Occupational Handbook (which provides job descriptions and median compensation figures for hundreds of professions).
It seems that most BLS data is available on the BLS Web Site (http://stats.bls.gov), including the Occupational Handbook (www.bls.gov/oco/). If that doesn't do it, call the BLS. To get employment-related statistics, call 202-606-6199. Other D.C. numbers include 202-606-5900 (publications) and 202-606-5890. The New York telephone number is 212-337-2400.
The Occupational Information Network, developed for the BLS by O*NET, describes various jobs and the people who do them (http://online.onetcenter.org). The Network replaces the Dictionary of Occupational Titles.
