If you are a university student or faculty member, you will be able to access subscription-based resources through your library’s web access. At Columbia Business School, go to: http://www.columbia.edu/cu/lweb/indiv/business/. Select a database (many of which can be accessed anywhere), and log on to the sites using your unix id (the first part of your email address, do not add "@columbia.edu") and enter your password.

• S&P (Standard & Poor's Market Insight) is very comprehensive. You can look up a symbol, type in a company or ticker, and receive a plethora of relevant information: company profile sheet, financial highlights, competitive analysis (comps that you can download into excel), corporate actions, news, etc. A (limited) educational version of Market Insight is available in the Student Edition of the web site for the Penman book.
• The Business & Company Recourse Center is good for a basic company overview. Type in your company name, key word or ticker- and you will get SIC & NAICS codes and key officer & company data. You can also find news, investment reports (from Investext), financials, rankings, and an industry overview- based on SIC codes. You can also get information on private companies (although not much).
