Several business databases have the option to limit your results to case studies:
In ABI/Inform database, click Advanced Search, type in your keywords, select full-text or peer-reviewed if needed, then scroll down near the bottom of the page and select "case study" in the Document Type box.
Business Source Premier database opens to Advanced Search, so simply put in your keywords, and select Case Study in the Document Type box, plus any other relevant limits.
In Business Insights Global database, select Advanced Search, enter your keywords, then select Case Studies in either the Content Type area or Document Type menu, plus any other relevant limits such as full-text.
