I’ve never encountered a complete description of what the magazine wants its checkers to check. A managing editor took a stab in 1936: “Points which in the judgment of the head checker need verification.” New checkers, upon receiving their first assignment, are instructed to print out the galleys of the piece and underline all the facts. Lines go under almost every word. Names and figures are facts; commas can be, too. Cartoons, poems, photographs, cover art—full of facts. Opinions aren’t facts, but they rely on many. Colors are facts. Recently, a short story by Clare Sestanovich made a passing reference to yellow bird poop. The checker consulted ornithological sources. Would a bird poop yellow? Maybe, if it had a liver problem.journey-inline-newsletterinline-newsletter
