If you can’t make the trip up to Baltimore this week for the country’s biggest convention dedicated to crime fiction, you can at least meet two of Bouchercon’s guests of honor in D.C. tonight. Barbara Peters and Robert Rosenwald, owners of the Poisoned Pen bookstore/publisher in Scottsdale, Ariz. (and winners of Bouchercon’s 2008 lifetime achievement award), are at the Library of Congress, speaking on the topic “Books—-Before and Beyond: Publishing in the 21st Century.” Among the subjects under discussion are book trailers, game-book tie-ins, devices like the Kindle, and other initiatives that are likely to have a modest-at-best impact on book sales in the future. The event starts at 6 p.m. at the LoC’s Montpelier Room.
