The Los Angeles Times has a new books editor. He’s David Ulin, 44, a longtime champion of West Coast writers. He’s “written for numerous publications, including The Times, and served for three years as book editor of the Los Angeles Reader. John Montorio, the top editor of The Times’ feature sections, said that Ulin would be empowered to accomplish a complete makeover of book coverage when he starts in October. “I think that the review will remain urbane and sophisticated, but we want it to be far more accessible and far more attuned to what is really hot in the book world.”
