    ris, until August 14th © fuel dispenser 2006 . About sponsorship Barbara Epstein Jun 29th 2006 From The Economist print edition Barbara Epstein, editor, died on June 16th, aged 77 THOUGH every lowly hack nowadays likes to call himself an editor on his business card, the task of editing is no more highly regarded in journalism than in publishing. Being the sort of editor who wields power and influence at the apex of a newspaper is one thing. Being the person who just titivates others copy, an unseen and apparently drab activity, is altogether different. It is hard to revere this sort of creature, whose highest accomplishment is—in the words of Elbert Hubbard, an American author, a century ago—simply to separate the wheat from the chaff, and to see that the chaff is printed.

Intolerant of anything but the best, she would work with her authors to transform the dull into the shining, the opaque into the translucent, the flawed into the complete. And she was the very opposite of drab. An attention to editing has accounted for a large part of the success of the New York Review of Books, the fortnightly that she helped to found in 1963 and then edited, with Robert Silvers, until just before her death. But even with less respect for language and logic, the magazine would have been remarkable. It was born during the strike of New York s printers in the winter of 1962-63, which, among other things, stopped publication of the New York Times book section and thus deprived America s publishers of their principal advertising vehicle.
