"This year marks two centuries of the Ordnance Survey in Ireland. Finnian O Cionnaith [has provided] a succinct summary of the origins of what was described by the Freeman's Journal in 1824 as a ''great national undertaking". (Patrick J. Duffy, History Ireland, 2024)
“The publishers are to be congratulated on the high standards of production evident in this book … [O’Cionnaith’s] book is a valuable addition to the library of modern research available on the history of the Ordnance Survey of Ireland and appropriately marks the bicentenary of this institution which continues to have a positive effect on this country.” Mary Clark, Irish Archives, 2024
