Ireland playing catch-up when it comes to releasing official records

That importance, and the potential for hijacking a shared past for political advantage, suggests that all relevant records should be released simultaneously, if at all possible.
To that end, the Minister for Arts, Heritage and the Gaeltacht, Heather Humphreys, decided, two years ago, to publish State archives after 20 years, rather than conform to the heretofore norm of 30 years. This was done to match the practice in Britain. The long, and often fraught, interaction between the two jurisdictions suggests this is at least desireable.
