From the introduction:
The study of folklore, or folkloristics, is predicated on two premises: traditional expressive culture circulates across and within social networks, and discrete "performances" of traditional expressive forms serve an important role as the locus for the ongoing negotiation of cultural ideology (norms, beliefs, and values). The underlying assumption is that folklore emerges from the dialectic tension between individual members of a cultural group on the one hand and the "traditions" of that group on the other. This ongoing tug-of-war ensures that traditional expressive culture is constantly changing, adjusting to the needs of the individuals within a group."
