Readings, References, & Resources

In true academic (lecturer) tradition, we like ‘readings’. The following are a selection of appropriate readings and references to help you both further understand issues relating to qualitative methodology, as well as to offer potential sources to cite within your proposal and/or dissertation. This is, and will always be, very much a work-in-progress, and will be added to regularly. Most of the books and articles mentioned should be available via your institutional library, but if you have difficulty in finding them, do drop us a line craig@ttd.education and we shall try to assist where possible.
