A case study is a research approach that investigates a topic or issue by focusing on a representative person, group of people, or other sample. Observations and conclusions gained through these focused investigations are then (tentatively) applied to larger populations.
Case studies are often used in the social and health sciences, but may also be employed in other subject areas. A good case study avoids overgeneralisations, is forthcoming about its limitations (such as small population sizes), and examines a wide range of factors that could explain a particular outcome.
A case study allows researchers to investigate large and complex problems in a manageable way. It's not always possible to look at an entire population, but identifying a representative sample allows researchers to draw conclusions that may apply beyond the sample size.
Case studies will often:
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.
