Kila2008,
As I don't yet live in Ireland, I can't help you locate the book, (except to say try amazon or eBay), but I can put you in touch with a great bunch of people who may be able to help you with your research.
I hope no-one minds me posting a link to an other forum, but Self-sufficientISH is an international bunch of people who try to live sustainably within the confines of modern life.
