Jan Vansina’s 1961 book, Oral Tradition, was hailed internationally as a pioneering work in the field of ethno-history. Originally published in French, it was translated into English, Spanish, Italian, Arabic, and Hungarian. Reviewers were unanimous in their praise of Vansina’s success in subjecting oral traditions to intense functional analysis.Now, Vansina—with the benefit of two decades of additional thought and research—has revised his original work substantially, completely rewriting some sections and adding much new material. The result is an essentially new work, indispensable to all students and scholars of history, anthropology, folklore, and ethno-history who are concerned with the transmission and potential uses of oral material.
