Carissa Phillips at the University Library has created a guide to resources for industry information.
In addition to company profile information, Hoovers publishes First Reports, which include industry trends, forecasts, ratios, and "Call Prep Questions." In addition to Industry Profiles, there are State & Province Profiles, Sales & Marketing Templates, and Industry Prospector (building an industry list based upon metrics).
Note that you can only access these reports from the UIUC campus network or the VPN. If you're off-campus and don't have access to the VPN, see the box at left for other options.
