Guide to citing unusual sources

While looking online for an example of how to cite a Harvard Business School case study, I ran across this excellent citation guide (PDF) put out by the Harvard Business School itself. The guide is based on the 15th edition of the Chicago Manual of Style. In addition to instructions on how to cite the more commonplace items like articles and books, there are dozens of examples of how to handle trickier formats, such as:

• advertisements
• analyst reports
• annual reports (printed and online)
• bond prospectuses
• cases (printed and online)
• email
• government documents
• interviews
• legal cases
• marketing reports
• news web sites
• press releases
• SEC documents (printed and online)
• television programs
• working papers (printed and online)

There is also a nice section detailing how to cite sources or data found in databases, such as:

• Bloomberg
• Compustat
• CRSP
• Euromonitor GMID
  
• Gartner
• Hoover's
• ISI Emerging Markets
• OECD
• Standard & Poor's NetAdvantage
• SDC
• Thomson Research
