These border datasets conform to the Historic Counties Standard (HCS). The HCS Definition A datasets treat detached parts of counties as part of their host county, whereas the HCS Definition B datasets include them separately.
The full-resolution polygons are suitable for 1:5,000-scale applications. The simplified sets are usable at scales greater than 1:50,000. A set of border lines is also available, for applications where a coastline is provided separately.

Where there is nothing listed in the Definition B column, this is because the county has no detached parts and therefore the data in the Definition A column are suitable for either HCS definition.
