Barrow, Craig, and Diana Barrow. "Le Guin's Earthsea: Voyages in Consciousness." Extrapolation 32,1 (Spring 1991): 20-44. This essay was published just as Tehanu appeared, so most of it focuses on the first three parts of the Earthsea series. The authors spend some time connecting native American folkways to the Earthsea series.

Bittner, James W. Approaches to the Fiction of Ursula K. Le Guin. Ann Arbor: UMI Research Press, 1984. This is a revised dissertation, but it is a fine one suggesting many ways to analyze and group Le Guin's novels.

Bucknall, Barbara J. Ursula K. Le Guin.

New York: Ungar, 1981. This book in Ungar's Recognitions series is similar to a reader's guide to Le Guin, but it is insightful and well done, tying Le Guin's speculations in The Language of the Night to Le Guin's work up to 1980.
