Most useful probably would be to review the last 3-4 years of George Kolbe sales - I am pretty sure most if not all early copper literature has appeared 2-3 times if not more during this time span...I am not sure all the catalogs/PRL are readily available on Mr. Kolbe's website but you may be able to purchase them from Karl Moulten.
