The Libraries has access to the HBS (Harvard Business School) Case Studies database, which offers "2,000+ Harvard Business School case studies that provide immersive real-world scenarios and commentary to help students examine issues related to the dynamics of business."

IF that database does not contain the case study you need, they are available for purchase individually via the Harvard Business Publishing website (see link below) or you may request them via Interlibrary loan.

Some faculty make them required textbook material, and in that case, they would be available in the textbook section at the University Bookstore.

See the Business Research Guide for more information.
