The Folklife Archives was founded 1913. Themed questionnaries (directives) were used from the start but irregulary. In the 1930's the directives started to be used on regular basis. In the beginning, the correspondent reported not only his own experience but also other peoples experiences from their home location. The writers panel of today only report personal experience.
