Aging covers and those that miss their mark and lead to sluggish sales are often targeted for makeovers, many times with good results. Up to 75 percent of Viking's books get redesigned, says Assistant Art Director Jim Hoover, because the publisher sees it as a chance to reintroduce a book to the market. Makeovers are considered the fountain of youth for books, and Cynthia Voigt's "Izzy, Willy-Nilly" (Atheneum, 1986)--which went from sporting a frumpy illustration of a reclining girl to a cool headshot of a blond teen--is one example that has stood the test of time, thanks to the power of Botox for books. Teens are smart and savvy--and they know what they want. They'll gladly shop in the adult fiction section, and publishers know it. "For this reason, we tend to make our books look older," says Hoover. "Designers are always trying to push the envelope in this regard and come up with something that will stand out." In this article, the author discusses things that librarians should consider when they decide to do a collection makeover.
