The Valuation Office Revised Books, also known as the Cancelled Land Books, are updated versions of Griffith’s Valuation and date from 1850s to the 1970s. The manuscript books show any changes to occupier, landlord, tenement, size of holding or rateable valuation that occur during that time. The books are housed at the Valuation Office Dublin and are currently only available to visitors to that office; see Valof.ie_genealogy_Public_Office
