Obviously, having never met the man, the best way to remember him is through his monumental body fo work. It would be daunting to start anywhere, as so much of Updike’s work is considered essential at worst, canonical at best.
“His body of work is so large and thoroughly lauded, his achievements by now so familiar — the casual erudition, the inhuman rate of production, the pioneering application of top-flight, literary-descriptive prose to vaginas, breasts, penises, and bodily excretions — that it’s hard to see any of it fresh,” writes Sam Anderson of Vulture. “It can be intimidating. Dipping into his work sometimes feels like going for a day hike on Mt. Everest. What’s the point?”
The point, as Anderson notes, is that your life will be enriched. Tom Mallon has a lovely grace-note here. You can read online archives of Updike’s work at The Atlantic, The New Yorker, The New York Review Of Books, and The New Republic.
