I beg to differ. Hemingway wrote, up to about 1954- without flaw. He would spend hours writing longhand while standing up, on yellow legal pads, then return later and edit and crop and re-write until he had it 100% right-Did he make errors- Hell yes, but he caught most of them, or else Charlie Scribner did--When a critic review his "Green Hills of Africa" he had negative comments about the rough language- Hemingway replied: "That's how men talk on a hunting trip or safari"_ and he was right.
Any book devoted to any aspect of his life: his guns, his wives and women, should be letter perfect. Of all the books about EMH I have read and re-read, only one fits that category- so far. Bernice Kert-1983 W.W. Norton & Co. Book is well titled: "The Hemingway Women- Those Who Loved Him- The Wives and Others"-- By comparison, EMH's last wife, the late Mary Welsh Hemingway's book "How It Was" is laden with errors, but the photos make it worth a cursory read.
I am a cheap SOB by nature, hate to pay top dollar for flawed goods- shotguns that miss-fire, books with typos that someone should have caught--RWTF
