There is an interview with Paul Auster here. Among other things, he talks about his writing implements: "I do have a few unusual writing habits—I'm a dinosaur now. I write everything by hand and type it up on an old manual typewriter, an Olympia 1961 ... I've never been able to compose on a keyboard. I need a pen or a pencil in my hand, feel that it's a very physical activity. When I write, words are literally coming out of my body.
And: "I'm very particular about my notebooks, and 95 percent of the time they are the same kind of notebook: They're made in France and are very tall—Clairefontaine brand, 24 x 32 centimeters. They're filled with pages of graph paper, which I like, as my handwriting is rather small."
You knew this, at least since Oracle Night, didn't you?
And: "I tend to buy notebooks whenever I travel. I have Norwegian notebooks, Japanese notebooks, Australian notebooks. I write with a fountain pen, and over the years I've experimented with many different kinds of fountain pens, but for the past decade or so I've been using an Italian brand called Aurora. I do write with pencils, too, and those are always Pentel mechanical pencils with 0.5 leads. I told you I have small handwriting!"
These quotations do not make for the most important parts of this interview, of course. But I must say that I am a bit surprised by the fact that he has not taken at all to the computer. In fact, for some reason, he was the last writer from whom I would have expected this. It's just more (anecdotal) evidence for my theory that in writing there is much less of a relationship between the tools you use in writing and the output you create than some people would like to believe.
Most people who also like paper notebooks and mechanical pencils—like me—produce mainly crap. (Nor is this changed, if they change to software program(s) to store their notes and compose their prose.)
Perhaps I should note here as a counterpoint that I would have been really disappointed, if Auster had used a program like Scrivener. Just doesn't seem right ...
