“The market for books in Spanish, already among of the most promising in the publishing industry, is about to get a lot bigger. Barnes & Noble Inc., is adding thousands of new books to its Spanish-language sections… Books in all categories will be added, from self-help to literary fiction. And Barnesandnoble.com has started Libros en Espanol, an online service that includes author interviews, a best-seller list — topped by the Spanish edition of Sen. Hillary Rodham Clinton’s memoirs — and a guide to Barnes & Noble stores that sell works in Spanish.”
