The success of the series sparked a new interest in the guides and facsimile copies of the 1863 edition became an unexpected best seller in the UK in 2011. In the 14th episode of the series, "Batley to Sheffield", Portillo met a great-great-granddaughter of George Bradshaw, who showed him part of the family archive.
