This week Ireland celebrated the centenary of the first Dáil in 1919. An article on IrishCentral.com tells the remarkable story of the prison break of Joe McGrath TD (a member of the Dáil), Barney Mellows and George Geraghty from Usk prison in Wales on the same day. The three Republicans pretended to be American tourists and tried to head for the ferry in Fishguard but couldn't get a train.
The Internet Archive has released a wealth of scanned books published in 1923, the majority from the University of Toronto Robarts Library. Adding "Ireland" to the search results brings back an interesting collection of books such as The Irish Revolution and How It Came About, Pagan Ireland, and most interestingly, Michael Collins' Own Story.
The BBC Archive Twitter account posted a fascinating video of writer Frank Connor talking about his native Cork in 1961. While his nostalgic meanderings about Cork are somewhat interesting, the real gem here is the footage of inner city Cork from 1961 and its inhabitants going about their daily lives.
