Want to help save a classic bookstore? Two literary institutions are looking for assistance and offering deals. Hue-Man Bookstore & Café (2319 Frederick Douglass Blvd., nr. 124th St.; 212-665-7400), one of the city’s last black-owned bookshops devoted to African-American authors, will close July 31 after ten years in Harlem. Owner Marva Allen has applied for a $250,000 grant from Chase and Living Social to help her fund “the bookstore of the future,” but she’s also hosting an ongoing liquidation sale; all titles and merchandise are now half off. Downtown, the defiantly grassroots, communist-leaning Revolution Books (146 W. 26th St., nr. Seventh Ave.; 212-691-3345) is trying to raise $40,000 through used-book sales and online donations (revolutionbooksnyc.org)—so they can stay in Chelsea without, you know, help from any big banks.
