Does anybody have any suggestions for Irish History, Irish Myth/Religion, and Irish Folktales?

My library has tons available and I'm a bit overwhelmed.  To make things even more difficult, there's no option to only search non-fiction.  Any help is greatly appreciated!

You might want to read How the Irish Saved Civilization.  However, read it tongue-in-cheek, as I have also read How the Scots Saved Civilization, How the Indians Created our Civilization and others.  I may not remember the titles exactly, but they are close.

Thank you for the suggestions, Thomas.  

The Great Hunger, by Cecil Woodham Smith, is a gripping story of the Irish famine of 1845 - 49 that killed a million and a half people and drove another million to the New World in "coffin ships". 

It's been added to my list.  Thank you, Bonnie.

I know this is an old post, but I liked Wars of the Irish Kings by David McCullough.

Thank you, Polbio and Linda!
