History in the Ordnance Map An Introduction for Irish Readers

"This book describes the principal maps of Ireland and parts of Ireland produced by the Ordnance Survey of the United Kingdom over a period of nearly a hundred years, beginning with the establishment of the Survey's first Dublin headquarters in 1824 and ending in 1922 with the creation of separate government survey offices for the Irish Free State and Northern Ireland. Its aim is ... to indicate the type of information available to researchers from maps and associated documents at different scales, in different formats, and for different times and places." --Preface.
