Get ready to gaze upon titanic collections, smell the musky scent of aged paper, and touch what you’ve never touched before: Seventy-five exhibitors from the United States, Canada, and Europe are offering “rare books, manuscripts, autographs, prints, maps, drawings, and other fine memorabilia” at the 27th Annual Washington Antiquarian Book Fair. There will be more than 2,000 experienced collectors and browsers there—united by a common love of, well, old stuff. Rare stuff. Cool stuff. There’ll even be people present in the afternoon who can appraise your stuff, if you bring it. So fish out that hundred-year-old copy of Leaves of Grass and make friends with your fellow bibliomaniacs from 11 a.m. to 4 p.m. at the Holiday Inn Rosslyn, 1900 N. Fort Myer Drive, Arlington. $6. (301) 654-2626. (Jennifer Agresta)
