Love is in the air. People are buying chocolates, flowers and luminous cubic zirconias (since we all know times are tight). But did you ever wonder why? When did all this begin? The library has so many resources to answers all your Valentine's Day questions. You can use our computers and check out what the History Channel says. You can research our databases  and find out details about the holiday. How about checking out a book on St. Valentine , himself? So, now... love is not just in the air, it's in the library, too. Happy Valentine's Day!
