Looking for quick answers to some of the most common business reference questions? Check out the "Fast Answers" page from the Baker Library | Bloomberg Center at Harvard Business School. In just a few clicks I can find business demographics, historical exchange rates, industry information and just about anything else I can think of. Not everything they point you to is free but some of it is. And if they point you to a database, you can check your local library and see if you have access. Harvard even offers cheat sheets on how to use most any business database available. These can be very helpful if you've got access and need to become familiar with all the features of a particular database. Teach yourself how to use a few new databases and you've suddenly got some new skills to add to your resume.
