For example, Chesham is a village in the town of Harrisville. The ODP does not have a separate category for Chesham, and web sites that have a Chesham address are listed with the other sites in Harrisville. Clicking on the link for Chesham will take you to the Harrisville category.
A few of the larger or well-known districts do have their own subcategory, such as Weirs Beach in Laconia. Only sites that deal with the district as a whole are listed in the subcategory. Sites for individual businesses, churches, and other organizations are listed in the larger locality.
