Many thanks to Rainer, who left a comment on one of my reviews of a James Purdy novel, alerting to me the special edition of Hyperion Writers' Journal dedicated to Purdy. This is a fantastic resource. I've only dipped into some of the papers included, and I'm looking forward to reading them all in detail.
The more I think about Purdy (and I do, frequently, his writing keeps coming back to me), the more I think he is a neglected genius. When I'm done with my PhD I aim to make a fuller study of his work, and I'm really pleased that the Nietzsche Circle, publishers of Hyperion, have produced this special edition.
It is also a wonderful website, and as an amateur dabbler in Nietzsche, I'm much looking forward to browsing further.
