This survey of the Blé language group of southwestern Burkina Faso was conducted by John and Carol Berthelette in February 1994, with Assounan Ouattara and Soungalo Coulibaly revisiting the village in 1995 to carry out bilingualism tests, and John Berthelette revisiting the area in 1997 to conduct individual questionnaires. The survey had as its goals: to gather basic demographic facts about the Blé people group; to elicit and record a word list in the Blé language; to determine the Blé's attitudes toward and competency in Jula, the trade language of southwestern Burkina Faso.
