Robert Caro's essentials

"2. My Typewriters I write my books not on a computer but on a Smith Corona Electra 210. They stopped manufacturing them about 30 years ago, but I have accumulated some. You need spares because when a part breaks on the one you’re using, you have to cannibalize the part from another one. When I have a book coming out, and newspaper profiles mention that I use them, people send me their old ones that were stored away years ago. Thanks to this generosity, I had 14 of them three years ago. I’m down to 11 already."
