Some years ago (in 2010, I think) I gave an interview about the experience of doing a Ph.D., as part of an Institute of Historical Research project on the past and future of the history doctorate. For completeness, I make it available here.
Amongst other things, it reflects how different my Ph.D. would have been had resources such as Early English Books Online been available in 1998. The interviewer is the redoubtable Danny Millum (@ReviewsHistory)
