Barely a month after leaving Random House, where he was editor of such bestsellers as Seabiscuit and The Orchid Thief, Jonathan Karp has been named as the pubisher of a new imprint at Warner Books. As Hillel Italie reports in an Associated Press wire story, the new imprint will be called Warner Twelve, because it will publish only one book per month. “The idea of being both the publisher and editor of the books I work on is something I’ve aspired to my entire career,” Karp tells Italie. “And I love the idea of only publishing 12 books a year. It’s so hard to get people to pay attention to books and the best things a publisher can do is lavish its own attention.”
