A work of particular interest to CR has been recently posted to Sacred-Texts.com: Survivals in Belief Among the Celts, by George Henderson, [1911].

This long out-of-print book, graciously loaned to sacred-texts for scanning by a reader from their personal library, reviews the extensive literature on survivals of pre-Christian beliefs in the Celtic area. It covers customs from Ireland, Scotland, the Isle of Man, Cornwall and Brittany, and relates them to other traditional cultures world-wide. This is a work of scholarship, and cites from authoritative literature, including many now hard to obtain sources, and several short texts in the original Gaelic. Among the fascinating topics covered are the evil eye, geis (taboos), doppelgangers, beliefs relating to animals and shape-shifting, lustration, second-sight, and healing rituals. Of particular interest is the discussion of pagan elements in the Carmina Gadelica.

Published at Glasgow university, it focuses on the traditions of Scotland and Ireland. It is because of works like this that we should support Sacred-Texts. There really is no other sourse like it out there. Consider buying their CD soon.
