Case studies are often published in journals for an academic or professional audience. When searching you will need to keep this in mind, and use appropriate discipline-specific language to increase your chance of success.
Many of the library's databases will allow you to limit your results to case studies. Look for options to do this in fields like document type, publication type or article types.
If you don't see an option to limit to case studies on the database you are searching, you can include "case study" or "case studies" as a search term.
The following are a selection of databases which include case studies:
