Buckinghamshire Colour Tithe Maps

TheGenealogist continues to set itself apart from the larger genealogy companies with unique content like the new colour maps for Buckinghamshire just added to their National Tithe Records collection.
Search by name and keyword (for example parish or county) to find everyone from large estate owners to occupiers of tiny plots such as a cottage or a cowshed.
The tagged 19th century colour maps are sourced from The (UK) National Archives and available to those with a Diamond subscription.
In addition to Bedfordshire the collection includes many other Home counties and beyond including Norfolk, Shropshire, Staffordshire, Suffolk -- I was unable to find a complete list.
