Dear Ms. Wheat, You may want to post this query of ARTIFACT, the listserv on material culture study and methods. They are a very helpful group and, I would imagine, have some good advice. The address is ARTIFACT%UMDD.BITNET.BROWNVM. I hope this helps. With every good wish, Steven ********************************************************************** Steven R.
