Folklorists and anthropologists have collected oral narratives, etc., 
from Southern African Americans discussing conjuration, etc., for more 
than a century Some of the earliest published academic references in 
folklore date to the first quarter of the twentieth century. One of the 
earliest discussions of hoodoo appears in the book _Folk Beliefs of the 
Southern Negro_ by Newbell Niles Puckett and published in 1926. \
