The following (necessarily incomplete) list shows the majority of categories relevant to this WikiProject.
- Category names in bold highlight major subject areas (to aid list navigation)
- Indented bullets show subcategories within a parent category
- Large sub-category sets (eg 'xxx by county') are summarised to avoid swamping the list
- Sub-categories belonging to multiple parents (from this list) are shown once, under the 'most appropriate' parent
- Project members are encouraged to add omissions to the list
