Later, my tastes got more sophisticated, and I began to read works by Asimov, Pohl, Clarke, Heinlein, Bester and so on.

All of this was more or less natural, because my parents were both involved in SF, my father as a very successful author and my mother as a literary agent. They encouraged me, and so I blame them. :)

My fiction library consists of several thousand books, mostly paperbacks; perhaps 75% of this is SF, the rest being mainline fiction, thrillers, that sort of thing. I also have a technical library of perhaps 3 or 4 hundred titles, mostly graphics, engineering, math, that sort of thing. Lots of titles on my hobbies.
