Here's a link to the site's reading list. As always, ymmv so take it fwiw.

Quite a long list. And, unfortunately for me, most of them I have not read.
Hemingway...I've read some of his short stories. Started on a couple of his long novels - got interrupted and lost the copies, you know the drill. That was back when I was far busier.
The writing style, of his Paris-era work, was quite different and a bit hard to read. His later, modern short-stories, much different.
But I came to a few conclusions: Hemingway was a successful writer - a great literary contributor. But as a man, he was not successful.
I had also read a bit of the dynamic between Hemmingway, Fitzgerald, Ford Madox Ford, and others in the Paris clique. I have never read Ford, who was a British writer Hemingway thought was pompous for the sake of being pompous. But Ford was equally dismissive, talking of Hemingway as "that boy from Oak Park" (Chicago suburb) who wanted to pretend to be manly.
(EDIT: Just checked. While Hemingway was repulsed by Ford, who was asthmatic and had hygiene problems...it was co-Parisan-refugee William Faulkner who was so contemptuous of Hemingway's background.
Also...I see I've misspelled Hemingway, all my life...)
It was probably a true criticism. Hemingway did start out soft - from an easy background. In that phase of life he was pretending to be a man, aspiring to become one.
He did succeed, after a fashion. He became much the man he sought to be - ambulance driver during the war, correspondent, great literary output.
But again, he failed. He was, what, 62?...when he took his own life. IMHO, suicide is failure. It's the ultimate white flag. It can be an honorable end - death before dishonor, in war, or a quick end to a wasting disease; but to just go and kill yourself on your large landholding, because you're frustrated or fear your career is over...is just weak.
