Jagerick-
I checked the site and I was able to find their publication, The Point
http://www.safepiercing.org/point.html). Articles on the history of body modification are few and far between. Unfortunately, they did not have properly or rigorously cited sources.
For example: Issue 22 "History of Body Piercing- The Ampallang"
http://www.safepiercing.org/PDFs/point22.pdf)
The author (Paul King) does not use proper citation methods. In fact, he actually just lists someone's name, Tom Harrison [sic], as his number 2, 3, 7, and 11th sources, rather than an actual publication source or verified on record interview. Paul King did not even properly spell this man's name, which is correctly spelled "Tom Harrisson." I was able to find a book that Paul King used
http://www.amazon.com/Penis-Inserts-Southeast-Asia-Bibliography/dp/0944613055), but the specific page numbers were not documented in his article.
Current anthropology/archaeology periodicals and books will have the most reputable cited sources which are essential for writing a solid research paper. For the original poster, this can mean the difference between having verifiable, reliable sources for a paper or facing disciplinary action for improperly or poorly cited sources.
