Now available for the Kindle ereader, S.T. Joshi’s Lovecraft and a World in Transition: Collected Essays on H. P. Lovecraft (USA Amazon). Also at the UK Amazon where it’s at a low £6.66 price. Even if you can’t afford that, I’d presume that the 10% free sample is still worth having since this whopper is some 650 pages long in print and Amazon claims 742 pages for the digital copy. Contents list is here. Not sure if there are round-trip linked footnotes / endnotes on the Kindle version.
