Maps of Dublin accompanying Thom's Official Directory

Nine Thom’s maps of the city and environs of Dublin from the collection of the School of Geography, Planning and Environmental Policy (GPEP). Printed by the Ordnance Survey for the Dublin publisher Alexander Thom from the six-inch map sheets 18 and 22, and dating from the late 19th century. The maps have been annotated with hand written dates made by Dr. Arnold Horner, formerly of GPEP, and based on information in J.H. Andrew’s article "Medium and message in early six-inch Irish Ordnance Maps: the case of Dublin city". These loose maps were originally published in Thom’s annual Almanac and Official Directory.
