The wealth of information and data available from U.S. Government sites is very valuable to businesspersons, but often times overwhelming for those trying to locate a specific piece of needed information. Columbia University Libraries has taken a good first step in making U.S. government sites more visible, accessible, and manageable. U.S. Government Documents Ready Reference Collection (http://www.columbia.edu/cu/lweb/indiv/usgd/rref/index.html) is an online collection of government documents arranged by broad subject category, such as Census & Demographics; General & Consumer; Education; Foreign Countries; Business & Economics; and more. The information and data is arranged by title, and each title has a note of its available format (pdf, html, excel) and frequency of publication. The Business & Economics section of the site includes many frequently used business titles such as the Consumer Price Indexes, Country Commercial Guides Market Research Library, The Employment Situation, FRED: the Federal Reserve Economic Data, the National Compensation Survey–Wages, Small Business Economic Indicators, and more. The listing is long enough to be comprehensive, but short enough to browse for valuable information you may not have known existed. A great site to bookmark and refer back to when conducting research for papers and projects.
