Join us for the 9th annual DEWEY DECIMAL DASH 5K RUN / WALK and support the Haverford Township Free Library!
This fun, family friendly event is for all ages and fitness levels and brings our community together to support our Library!
People who know Haverford Township know that this is a special place. It is a town where neighbors still know and look out for each other, where small businesses have thrived for generations, where residents feel real pride. Our Library, with 180,000 patron visits each year, is a gateway to community connection through social events, groups and programs that bring people together. Our Library is part of what makes this township an exceptional place to live.
With generous support such as yours, this event has raised over $100,000 since 2017, helping fulfill our Library’s mission of providing excellent resources, services and programs for all ages. In all, the Library hosts nearly 1,000 programs annually with 27,000 people attending. These range from the literary (author talks, a graphic novel club, the writers group) to the wide-ranging (Lego Club, Science in the Summer, Concerts in the Park, the Quilting Group, and Teen Mindful Yoga). Haverford Township Free Library truly offers something for everyone in our community. Thank You for Your Support!
Did you know that our Library has the highest circulation rates of all libraries in Delaware County? We offer a remarkably diverse collection of both print and digital materials and have earned prestigious recognition with the highest Gold Star designation by the PA Library Association.
