Johnson, R. B., Onwuegbuzie, A. J., & Turner, L. A. (2007). Toward a definition of mixed methods research. Journal of Mixed Methods Research, 1(2), 112-133.
This paper develops a definition of mixed methods research through a discussion of the views of many authors who have played an important role in the developing the idea of mixed methods research. The paper is useful because it provides insights into the diversity of ideas about mixed methods research. What is disappointing is the author’s suggestion that mixed methods research should be seen as a third paradigm in social research, thus endorsing rather unhelpful paradigm-thinking in research.
Greene, J. C. (2008). Is mixed methods social inquiry a distinctive methodology? Journal of Mixed Methods Research, 2(1), 7-22.
This paper provides a very useful discussion of the question whether mixed methods research can be seen as a distinctive methodology for social inquiry. What is particularly valuable is the systematic discussion of four methodological domains: philosophy, methodology, practical guidelines and socio-political commitments.

This is an interesting paper not in the least for historical reasons, as it is an early attempt to argue the case for a mixed approach. It’s depiction of pragmatism is not entirely accurate, although it reflects the state of the discussion on the role of pragmatism in the earlier phase of the development of mixed methods approaches.
