Six councils succeeding the former Clwyd County Council say they recognise that the release of the Jillings Report 'may bring distress to those affected by historic abuse'.
A redacted version of the report has today been published after 17 years following a Freedom of Information request.
Allegations of abuse centring on North Wales children's homes first emerged in the early 1990s.
John Jillings, a former director of social services for Derbyshire, was appointed to lead a full investigation into the affair when the scope of the allegations became more widespread.
North Wales Police described the inquiry as its 'largest investigation into child abuse' and said it resulted in 3,755 witness statements being taken with at least 24 victims identified.
