"Today is our second annual unofficial Harry Potter Day," announced Director of Library Services Emily Hollingshead. "This year we are doing the second book, Harry Potter and the Chamber of Secrets."
"We have a duelling class, a herbology class and a defense against dark arts class," she outlined. "The burrow is all set up to explore (and) we have a photo booth that people can take advantage of."
Participants were divided into classes named after the classes at the fictional Hogwarts School: Gryffindor, Hufflepuff, Ravenclaw and Slytherin. They competed for a silver goblet, which went to the Hufflepuff House.
Hollingshead thinks Harry Potter is so popular because it appeals to kids of all ages, including parents and even grandparents.
"They really do," she told Drum FM. "I think they appeal in different ways to different generations, but it means that people can enjoy it together and I love that."
Hollingshead expects they will soon begin planning for next year's Harry Potter Day.
