Powell's
I'm an affiliate with Powell's bookstore. which means if you order a something from Powell's via a link on this site, I receive a small percentage of the price of the item. I have a custom Celtic Studies Resource store here.
Some specialized Celtic studies books from Ireland and Wales are not available from Powell's, but they are available from Books for Scholars or your local independent book store special order them.
In case you're wondering why I'm not an Amazon Affiliate, you can read about my decision here.
Books for Scholars
Books for Scholars specializes in books for the Celtic scholar. They are absolutely wonderful. Their catalog is on the web site, and all the books are anootated. Just go there and look, and make a regular trip there, since they do keep up with Celtic publishing. Books are neatly divided into categories.
Three Geese in Flight Books
Three Geese in Flight Books has been selling antiquarian, used, and out-of-print Celtic and Arthurian studies books since 1976. They stock titles on the folklore, mythology and history of Celtic Ireland, Scotland, Wales, Cornwall, and Brittany, and specialize in the history, literature, fiction, and scholarly study of the Arthurian legend.They also feature Norse, Anglo-Saxon and Medieval studies books.
Oxbow Books
Oxbow Books is a British bookseller specializing in classical and medieval scholarly texts in language, literature, history, archaeology and the arts. They have an American partner, David Brown Books, who publish a price list in U. S. dollars and sell the books in North America. The web site is as full of information as the catlogs; I often find out about new publications here before I see a review in an academic journal.
