Gold Price Historical Data

From where can i get the historical comodity prices for Gold and Oil to the present date. I need 5 years data?

Barcharts.com has a good historical database of commodities prices. I think one of their services is free. If not there is an inexpensive one. If you are going to be trading commodities you certainly need a charting service to start.
