Todays Irish Times has a nice supplement on Easter 1916. Written in association with the Department of Education it is something that most Irish people could find useful not just school kids.
It discusses the background of the Rising, information about each of the men who signed the Proclamation of Independence, a day by day guide to the events, the aftermath, and a section on how the current political parties claim the 1916 legacy. There is also a glossy map of the battle sites. It's well worth purchasing, especially as the media will be full of discussion about 1916 and its impact over the next few weeks.
