Deletion of The Rivers and Beacon-Hills of Gondor

Comment: Most of Tolkien works have been studied to death, but right now I am also not seeing enough to make this essay notable. No, not everything penned by a notable author is notable,  requires 2+ reviews, or other indications of impact, and this is not shown currently (Tolkien Encyclopedia discusses it in a single paragraph: https://books.google.co.kr/books?id=by0dzzQ6m8sC&pg=PA159&dq=%22The+Rivers+and+Beacon-Hills+of+Gondor%22+-wikipedia&hl=en&sa=X&ved=0ahUKEwioifH9mPboAhXFw4sBHf_MDGMQ6AEINjAC#v=onepage&q=%22The%20Rivers%20and%20Beacon-Hills%20of%20Gondor%22%20-wikipedia&f=false; I don't think that qualifies as in-depth treatment). The source cited by Hog Farm (https://www.elvish.org/Tengwestie/articles/Hostetter/sindll.phtml) would pass in-depth, but how reliable is https://www.elvish.org/Tengwestie/ Tengwestië The online journal of the Elvish Linguistic Fellowship? See also https://www.elvish.org//Elvish Linguistic Fellowship. I am afraid this may be not scholarly but just scholarly-like fan analysis. PS. Still, all things considered, I am leaning towards that source being in-depth and reliable. If anyone can show another source of similar or higher quality that is in-depth I'd be willing to change my vote to keep. But right now I am not seeing it, and one passable source is not enough in light of our policies
