The study of oral tradition is distinct from the academic discipline of oral history, which is the recording of personal memories and histories of those who experienced historical eras or events. Oral tradition is also distinct from the study of orality, defined as thought and its verbal expression in societies where the technologies of literacy (especially writing and print) are unfamiliar to most of the population. A folklore is a type of oral tradition, but knowledge other than folklore has been orally transmitted and thus preserved in human history.
