So, thanks to Doug A. for pointing out the announcement of the forthcoming book APPENDIX N: THE ELDRITCH ROOTS OF DUNGEONS & DRAGONS by Peter Bebergal (Strange Attractor Press, 2021). This seems to be an anthology gathering together a selection of titles from the 1st edition AD&D Recommended Reading list --not a discussion of the stories, such as Jeffro Johnson's APPENDIX N: THE LITERARY HISTORY OF DUNGEONS & DRAGONS (2017), which I believe began life as a series of blogposts. Instead Bebergal is reprinting works by sixteen of the authors so named by Gygax back in 1979.
This "selection of short fiction and resonant fragments" are taken from sixteen authors, of whom eight are named in the article linked to above:
H. P. Lovecraft
The write-up also promises that the book will be accompanied by a chapbook novella of A. Merritt's PEOPLE OF THE PIT.
That seems to me a pretty good list, though the scholar in me cannot forbear to point out that Tanith Lee, while worthy of being included on her literary merits alone, did not in fact appear in Gygax's list. This suggests a certain slipperiness for criteria.* And I find myself curious as to the other eight authors might be.
One curious feature of the book is its presentation as a D&D adventure, GG1. Descent into the Temple of Appendix N, clearly a homage to Gygax's D1. Descent Into the Depths of the Earth (1978).
I think I'll pass on the deluxe 30 Pound version and hold out for the paperback edition to follow.
More on this one when I find out more. I'll certainly be on the look out for a more complete list of authors, and of what works are chosen to represent the authors already announced.

*Similarly, they speak of Virgil Finlay's having illustrated the chapbook, without mentioning that Finlay has been dead for almost fifty years
