STEVE INSKEEP, HOST:
For centuries, biographers have relied on letters to bring historical figures to life. You peer at the handwriting, and you can sense the thinking of Gandhi or Catherine the Great. But as people switch from writing on paper to writing with keyboards, biographers are finding new benefits, as well as challenges, to studying these documents. From member station WNYC, Ilya Marritz reports.
ILYA MARRITZ, BYLINE: The authorized biography of Apple co-founder Steve Jobs is based on dozens of interviews. But one of the book's juiciest episodes comes from a string of emails from 2003. That's when Apple launched the iTunes music store. Right away, the company's rivals at Microsoft understood this could be a game-changer.
WALTER ISAACSON: It was finally at 10:46 that night when Bill Gates weighed in by email.
MARRITZ: This is Walter Isaacson, author of the best-selling biography. The subject line of this email? Steve Jobs again.
ISAACSON: Steve Jobs' ability, he wrote, to focus in on a few things that count, get people who get user interfaces right and market things, is amazing. It was sort of a wonderful exchange, to know exactly what people were thinking at Microsoft when the iPod first came out.
MARRITZ: Right. I mean, you interviewed Bill Gates for the book. But he probably wouldn't have expressed himself quite that way, if you asked about that incident.
ISAACSON: You know, when you interview people, you get their recollections. When you have the letters or the phone transcripts or the emails that they did at the time, you find that it's pretty different.
MARRITZ: Isaacson is now working on a book on the dawn of the age of the personal computer. And he's having a hard time getting the material he really wants, despite landing interviews with people like Bill Gates.
ISAACSON: And a guy named Al Alcorn, who founded Atari; and they have a lot of great memories, but I couldn't really extract the emails from them.
MARRITZ: A lot of us think electronic communications live forever. But if someone won't give up their emails, or takes their passwords with them to the grave, or if they used software that's now outdated, their records may be lost. And so Harvard has John Updike's floppy disks. Emory has Salman Rushdie's emails. But these are the exceptions to the rule, says William Stingone, curator of manuscripts at the New York Public Library.
WILLIAM STINGONE: It's really only been the last, say, 10 years that we've started to address it seriously; knowing that most of what's going to be created from here on in, is going to be created electronically.
MARRITZ: In September, the New York Public Library will make public the archives of Timothy Leary, the psychologist who popularized LSD. He was also a computer enthusiast. Crucially, this archive will be entirely searchable by keyword.
STINGONE: So that's the real leap because what you find, once you have this massive amount of text - that you could pretty much put in any word you could think of, and find something.
MARRITZ: Searchability made a difference for D.T. Max. He's the author of a biography of the novelist David Foster Wallace, who committed suicide in 2008. Max says Wallace frequently described his moods in emails to his friends, like this one to fellow novelist Jonathan Franzen.
D.T. MAX: Where he talks about how he can't write, and he's brooded on it over and over until his brooder is sore. And I remember brooder - you know, it's a made-up word, was such an easily searchable word that I remember searching for that when I was trying to locate the exact phrase to put into the book. And you just think, wow, what a lovely - what a lovely image.
MARRITZ: There are other emails Max never got to see. Wallace's friends and acquaintances told him about these messages, but weren't able to recover them.
MAX: So that kind of explanation - it's on an old computer, and I don't know if I can find it - kind of became the successor to all the other heartbreaking things that biographers, you know, have heard over the decades - like "we had a flood," or "I think it's somewhere in the garage." So it's a new form of defeat for biographers.
MARRITZ: Technically speaking, emails and instant messages may never really be lost. But some of them are nearly impossible to find. Max's advice to biographers: Get some training in computer forensics before you start your research.
