The Imp of the Perverse.
"Electronic literature?" I remember asking him. "What's that?"
"Check it out" he advised. I did, and while I remained (and remain) a pen-and-ink, printed-page person, for whom the computer is a handy office tool, not a literary medium, I was impressed enough by his Thinking Outside the Box to become an official (though passive) advisor to the Electronic Literature Organization. Bob too, as far as I know, did not himself practice what he took so energetic an interest in. To think outside the box is not necessarily to go there: his impish, always-lively oeuvre consists of printed pages.
Impish, yes: from his earliest novel (The Origin of the Brunists, winner of the 1966 PEN/Faulkner award for best first novel of that year) through his latest (Noir, 2010), his signature mode has been the Bad-Boy wink. Some years ago, when a reviewer characterized one of his novels as "unremittingly malevolent;' its author was delighted.
The Peck's Bad Boy of Postmodernism? The PoMo Puck? Take your pick. Abrazos, Comrade Coover!
