Value Line is updated weekly. The industry overviews are updated at staggered intervals, with each industry's overview typically being updated three or four times a year. A typical issue of Value Line contains about five industry updates. It covers 24 of America's key industries, with frequent references to foreign competition. Business week is kept on the third floor of the library.
Recent issues are in magazine format.
Older issues, dating as far back as 1976, are on microfiche. Some imagination or resourcefulness may be required to find the desired information. Another way to find industry information is to look up a country's name, and then look for the name of the industry as a subheading. Both cover more than 165 countries of the world. For the most part, they do not contain much in the way of specific industrial analyses.
