"The case method of analysis involves studying actual business situations, written as an in-depth presentation of a company, its market, and its strategic decisions, in order to improve a manager's or a student's problem-solving ability. Cases typically investigate a contemporary issue in a real-life context. There are multiple issues to consider and many 'correct' or viable alternatives to solve the case issues are presented." --Encyclopedia of Management. (4th ed.). Detroit: Gale, 1999. (p. 71)
Case studies are often not available for purchase by libraries. Many need to be purchased by individual users.
