In this preface to the special issue on "Doing Case Study Research in Organizations" we define case study research, review common themes and discuss future directions. We note the value of personal research stories and reflexivity in enriching understanding of case study research practice and draw attention to the opportunities associated with broadening the definition of what may constitute valuable data. We also discuss approaches to obtaining access and review some ethical dilemmas of case study research. Finally, we underline the need for further reflection on the role of computer analysis aids, on modes of writing and communication, and on ensuring quality in a context of epistemological diversity.
