I read this doing research when it was first out in hardcover. Re-read it in 2004 as part of an ongoing inquiry into the exchange between folk tales and literary fairy tales.
An excellent resource which covers tradition as well as the changing attitudes towards the banshee's presence. Comprehensive coverage of oral and written sources, folk stories, early writings and recent fieldwork. A must for anyone interested in folklore.
Although thorough in its analysis of the data, the book lacks in the qualities of good, compelling writing. A too positivistic approach was taken regarding the folk subject, failing to tell a cohesive story through the data.
Basically a romp through the Irish Folklore Commission's binders of oral histories done in the 1930's and 1940's - if it dealt with a banshee, it's in here.
A stray reference in the notes made me realize banshee stories migrated into the coal valleys of Pennsylvania, and survived into the mid-20th century.
In our house growing up in the 1960s, my mother would still refer to anyone towelling off wet hair as "looking like a banshee."
