"The library that could not wait to open", Dumfries Neighborhood Library opened its doors to the public one year earlier than planned. Due to the availability of a leased site, the Prince William County Board of Supervisors switched the dates for Dale City and Dumfries.  The second neighborhood library, Dumfries opened its doors to the public on June 8, 1985.

In 1990, a literacy lab and tutoring room was dedicated. While the literacy lab no longer exists, the tutoring room dedicated by the Chinn Park Friends of the Library and is available to the public. Dumfries continues to serve the needs of a diverse community. The neighborhood library has a collection of 20,162 items that includes Audio Books, DVD’s and Videos. Dumfries now boasts seven Internet stations, fax services and has a photo-copying machine for public use.
