Griffith’s Valuation is an astounding achievement, a masterpiece of Victorian social quantification that measures every property on the island of Ireland with painstaking, pinpoint precision. But it is not a census, and to use it as a census substitute, you have to understand how it works.
Griffith was charged with producing a scientific basis for property taxation in Ireland, and that is exactly what he did. Every building and every field in the country was assessed in meticulous detail to produce a monetary figure that represented the income that property should produce every year. The results were published between 1847 and 1864 in a series of 301 volumes.
These volumes were a public statement of the property tax liabilities of the inhabitants of the areas they cover, and were open to challenge. So accuracy was paramount. And part of this accuracy was precision about the date of publication – property, then as now, was a moving target.
For researchers, those precise dates of publication can be very important: if your William Burke was in Boston in March 1856, that can’t be him in Castlebar on January 26th 1857.
So how do you get that precise date? Every volume has the date on its title page. And you can get to the title page by going through Askaboutireland.
Run a search (e.g. http://goo.gl/JFSkd8 ), then open up a page image in a new tab or browser window. If you want, you can then just click the “previous page” link until you get to the volume title page.
But each volume can have up to 500 pages, making that process mind-numbingly tedious. Here’s a shortcut: in the browser address bar, you’ll see something like “griffiths.askaboutireland.ie/gv4/z/zoomifyDynamicViewer.php?file=210173[…]”
The”file” in that address is made up of two parts, a three-digit volume number and a three-digit page number. The example above therefore refers to volume 210, page 173. If you want to go to page 1 of volume 210, just change that 173 to 001 in the address bar, hit “enter” and there you are. The precise publication date is usually about two-thirds down on the left. In the example, it’s January 26th 1857.
