Main article: Wikipedia:Ireland disambiguation task force
There are currently many anomalies within the Ireland (island) article and its sub-articles. While many of the "Main article:" links point to their respective ROI and NI sub-articles, some of the sub-articles clearly cover the island as a whole, while some are clearly ROI articles entitled "Ireland" - which may or may not have NI's information included. Some NI-only links lead to 'redirect pages' that seamlessly lead onto the equivalent ROI articles.
The meaning of "Ireland" often changes from state to island - often within a single article, and within templates too.
