A Century of Weird Fiction, 1832-1937 is listed as available March 2020. It’s a £45 academic book from the University of Wales Press here in the UK, and apparently tries to marry two currently active academic lines of interest. Firstly the focus on the aesthetics of “emotional effects” (mainly around feelings such as disgust) in the weird, and secondly the recent elaboration of the possible philosophical implications of the weird. The book has chapters on Poe, Machen, Blackwood, William Hope Hodgson, and Lovecraft.
