Only one novel. Only 1 award nomination. Weak bibliography, but notability bolstered by the fact that Marks was an associate producer of 60 Minutes, and the novel was reviewed by the New York Times, and optioned for a film adaptation. The book seems more famous than the author at present, so this is a pass for now.
World Fantasy Award Winners with no Wikipedia articles (Novella Category)
Works are all of short form fiction. 34 stories, 3 collections, 6 award nominations, plus 2 award wins, with numerous in-print reviews. Good Candidate.
A World Fantasy win for Best Novella, won the 2021 Campbell/Astounding Best New Writer, plus two other nominations. Although a novel-length work is forthcoming, and only two stories have been published to date. Her short fiction is novella length, and each was published by Tor in book form. Her SFE/SFWA status would preclude an article at this time, but that is countered by her Best New Writer win.
World Fantasy Award Nominations with no Wikipedia articles (Novella Category)
The author has 9 novels, 27 short stories, 2 collections, with 4 award nominations. He has attracted 11 in-print reviews. My tool only shows 2 short fiction to be in SFWA markets, and none of the novels, but the author is roughly within guidelines for an article.
Works in the Finnish language, and has a Finnish Wikipedia article at https://fi.wikipedia.org/wiki/Pasi_Ilmari_J%C3%A4%C3%A4skel%C3%A4inen. Only 1 short story appears in an SFWA-qualified publication. An English-language article is not recommended at this time, but would be a good choice once the English bibliography expands.
I believe the situation is: Daveed Diggs (who has a Wikipedia article), William Hutson and Jonathan Snipes created a rap song called "The Deep", which was adapted into a novella by Rivers Solomon (who already has a Wikipedia article). The ISFDB tracks "The Deep" as written by Rivers Solomon, with a note about the contributions by Daveed Diggs, William Hutson and Jonathan Snipes. The ISFDB also only cites Solomon on the award entries, whereas the WFA site states: "Rivers Solomon with Daveed Diggs, William Hutson and Jonathan Snipes". The Hugo Awards cites the work the same as the WFA site. It's unclear whether Diggs, Hutson, and Snipes were nominated or not, but if they were, their bibliographies are too light to be considered for an article based on their genre writings.
