Harry Potter came to the Ada Public Library for a party on Friday afternoon. Here,  Leah Conley is dressed as a student at the Academy, and Natalie Walton, youth services director, is dressed as Professor McGonagal. They play out a scene from one of the tomes of the wildly popular series. British author J. K. Rawlings fantasy novels appeal to adults as well as youth. In less than 20 years since the first book was published, more than 450 million copies have been sold. It's the best-selling book series in history with the books having been translated into 73 languages. (Monty Siekerman photo)
