“Core membership of the American Booksellers Association grew from 1,664 companies last spring to 1,712 this year, the trade group told The Associated Press on Tuesday, the day before the BookExpo America publishing convention and trade show begins in Manhattan. The association also benefited from the recent trend of sellers opening new branches, with ABA members now in 2,227 locations compared with 2,094 in 2014 and 1,651 in 2009.”
