It has been tempting, by the way, to rewrite these things. To redraft a book that is fifteen or twenty years old so that all the technology isn't dated, or what I now see as awkward writing left in. (Or to tone down parts of it. In The Forever Drug, the sex is past R and shading right into NC-17, and these days, I'm not as graphic about that as I used to be. But the books were of their time, and rewriting them would be a mistake.)
John D. MacDonald put out a collection of his old short stories once, twenty-five or thirty years after he wrote them, but instead of leaving them as period pieces, he went in and updated stuff like how much lunch or train tickets or the like cost, to make them more contemporary. The stories were still good, but that updating wasn't -- because the society in which the old pieces were set had changed enough so he couldn't easily fix that -- people listened to the radio, they rode trains, they talked about things in the fifties that people in the early eighties didn't even remember.
When people talk to William Gibson about Neuromancer, somebody always asks: Where were the iPhones, Bill?
Way off in a future I didn't think about ...
What else can he say? Predicting the future isn't what we do.
So with my backlist stuff going into the realm of ebookery, I'm fixing the typos and artifacts I spot -- and I'll miss some of those. Plus some bits here and there so that dates agree with ages and like that, and now and then, changing "gigabytes" to "terabytes ..."
Okay, I've put up four books in epub versions in the last week. I think I'll get back to the Matadors now ...
