Often deemed the finest convention of rare books in the world, the 63rd annual ABAA New York International Antiquarian Book Fair returns to the Park Avenue Armory this spring. Almost 200 exhibitors from 16 countries will be selling rare books, manuscripts, historical documents, and various other one-of-a-kind archival materials. History, science, religion, art, philosophy, politics, and every other imaginable genre will be featured—in the first-edition, of course. Highlights are sure to include a $225,000 British first edition of Harry Potter and the Philosopher’s Stone and an immaculate $2.5 million first edition of Copernicus’s De Revolutionibus. With prices beginning at $50 (and heading into seven figures), there’s a page-turner for every bibliophile. —Lucy Horowitz
