I helped a student in CIS 9000: Information Systems for Managers at the reference desk who wondered if we had Harvard Business School cases. I recalled that there are some cases in the Harvard Business Review, but I checked the list and none of the cases he needs are available. They all deal with IT issues in companies. The professor has provided them the link to order the cases.
Interestingly, I noticed this information at the bottom of a case study that is available in the HBR that "Harvard Business Review and Harvard Business School publishing content on Ebscohost is licensed for individual use by authorized Ebscohost patrons at this institution and is not intended for use as assigned course material." So, they really want students to purchase the case studies.
