The OPW is being described as being oversensitive, after it removed visitor books from historical sites in Wicklow and across the country amid fears about running foul of data protection laws.
The Irish Times reports the state agency is concerned it's storing up personal data and could run afoul of European data protection rules.
Sites including Kilmainham Gaol, Dublin Castle and Muckross House have been told to take the books away.
But privacy expert Daragh O'Brien from consultancy firm Castlebridge says the heritage body is overreacting.
