    These code are unfinished, and the authors invite commentary.  Author 
    permission is required to use or cite these codes prior to completion. 

    Burton, White and Bradley prepared the original codebook for this study.  
    Original coding was done principally by Bradley with assistance from Moore, 
    with Michael Winkelman coding several societies, and Burton and White checking 
    codes and coding several societies.  White assembled and recoded materials 
    from the original codebooks into the present codes and codebook.  These 
    variables are recoded from many different elements in the original.  The 
    coding was supported by NSF grants BNS-8304782 and BNS-8507685.

1113.  Contact Characteristics, regardless of Advancing Frontier, 
1114.  Advancing Frontier - movement of people or cultural shift - 
       . =  Missing data
       1 = No - absent
       2 = Miners, Rubber extractors, Labor recruiters
       3 = Traders, irregardless of 2, and govt' officials
       4 = Extensive labor recruitment 
       5 = Missions, irregardless of 3: Traders, Gov't officials 
       6 = New Settlers
       7 = Symbiotic - no advancing frontier - settled by outsiders 
       *   long ago, focal group resides in marginal area 

    where codes differ, 1st code is characteristics present,
                        2nd code those that have impacted as frontier
