Andy Wood’s Abandoned & Vanished Canals of Ireland, Scotland and Wales [Amberley Publishing, Stroud 2015] is now available. It is a companion to his Abandoned & Vanished Canals of England.
Many (but by no means all) of the Irish canals are covered on this site; the author sought and was granted permission to draw on this material and has generously acknowledged that.
I have not yet had time to read the book but I did note that the author seems to have confused Grand Canal Harbour and Grand Canal Docks.
