The document provides an introduction to folklore, defining it as the traditional cultural expressions of various folk groups, including tales, legends, customs, and beliefs communicated orally within communities. It traces the history of folklore studies, noting how early conceptions viewed folklore as belonging to illiterate or marginalized groups, but fieldwork in the early 1900s revealed the similarities between all human cultures. The definition of folklore then broadened to recognize that folk traditions can exist within any collective group. The document also examines different scholars' definitions of folklore and provides examples of topics that folklore can encompass.
