The Library is unable to acquire access to Harvard Business Review case studies as they have very strict licensing rules that do not allow for sharing copies. This also prevents us from borrowing these from other libraries via interlibrary loan, and, in fact, many libraries do not purchase these case studies at all due to these lending restrictions. We have some case studies in our Harvard Business Review Case Study Collection from EBSCO, but it is limited to about 2000 titles.
Unfortunately, individual purchase is the only option for obtaining these case studies from HBR.
