FAQ: How do I find seminal works on qualitative, quantitative, or mixed methods research design?

Case Study: Yin or Stake

Unfortunately, neither seminal text is available, however, have the following alternatives linked below.

Also see our Case Study page of the Research Methods & Design Guide.

Supplemental resources (especially books) are not necessarily in the Library, and might require that you obtain them through your local public or college library. You can search to see if a library near you owns the book. Search for the book, then on the book summary page enter your ZIP code in the "Enter your location" box to see if any local libraries own the title. Alternatively, you might want to consider renting or purchasing this book through Amazon, or another online book vendor. Click here to view the options available from Amazon.  
To find other publications by Robert K. Yin, we recommend a Roadrunner Author Search. Click here to access a search limited to the author and full-text resources (articles, book chapters, reports, etc.). 
Finally, we recommend using SAGE Research Methods to locate full-text e-books on case study research. To access SAGE Research Methods, go to Research Resources and select A-Z Databases
