In Monday's issue of the magazine, there's a look at books on the BP oil spill that publishers are crashing; a piece on Tachyon Press, which celebrates its 15th birthday; and an update on the challenges B&N faces after its proxy win. There is a profile of author Charles Elton, a rundown of some of the regional fall shows, and a feature on sports books with a "Why I Write" column by Dave Zirin.
