On Sunday, April 20, Idlewild Books will open near Union Square in New York City with an inventory of 6,000 titles, all of them arranged according to country. "I've always been a big traveler and reader so the idea of a bookstore organized by country -- with literature, guide books, books about politics and culture, and so on, all shelved together by place -- always appealed to me," said owner David Del Vecchio.
