I found some information at http://www.cs.utexas.edu/users/cline/papua/core.htm . I wonder if SangKeum is OK or not.
And I found another source ; "You can visit West Papua and discover for yourself the uniqueness of the country's environment and people. Helpful resources are Kal Muller's book Indonesian New Guinea, and John McCarthy's booklet".
Let me find the books.
