Here you can find a list of suggested reading if you wish to delve into the depths of this wonderful, complex tradition. I’ve splitted the texts in 2 broad categories: 21st Century (modern research and updated historical/archaeological information), and 19th/20th Centuries (books written around and during the Celtic Revival times, which are good to see how THE STUDY of Gaelic Ireland’s traditions developed).

Volumes I have personally found particularly meaningful and impacting are highlighted in bold.
