I had thought Iorwerth Griffiths' [i:2u0tm7ks]Complete Guide to Beer & Cider in Ireland[/i:2u0tm7ks] (review here[/url:2u0tm7ks]) was out of print but I notice that Chapters on Parnell Street in Dublin have new copies of it on sale for €4.99.
As a guide it's getting very out of date now, but is still worth having for the historical stuff at least.
