Discovering Our Past. Ashmore & Sharer.
Systems of exchange serve to provide populations with commodities which are otherwise inaccessible, such as raw materials which are not locally available (Ashmore and Sharer 2000: 190).
It is necessary to differentiate commodities which are acquired through local or interregional exchange from other commodities. When material goods can be recognized as having been purposely and cooperatively exchange between communities, a further understanding of the systems of trade and exchange which governed these transactions advance research into the prehistoric economic systems of the community or communities in question. Research into, and perhaps the eventual reconstruction of, the prehistoric economic systems of Palmarejo and the surrounding region will enable a better understanding of the society as a whole, and interregional and interpersonal exchange serve to circulate beliefs and ideologies as well as materials, and so an understanding of the prehistoric exchange systems involved allow for inferences into cultural change patterns and mechanisms (Ashmore & Sharer 2000: 190).
Archaeological data comprise either goods necessary for subsistence, such as food or storage vessels, or non-subsistence goods, such as luxury items like jade and obsidian or specialized craft items like serving vessels. Such categories are among those necessary to distinguish in regards to archaeological remnants in order to categorize and inventory remains for the purpose of better understanding the means involved, including the geological source of the raw materials, the sociopolitical source of the craft produced, the various networks within which the item traveled, the terminus of the item's in the exchange of the items (Ashmore & Sharer 2000: 192).
Because exchange often involves nonperishable items which archaeologists can later utilize to investigate and reconstruct the mechanisms, routes, and systems involved in prehistoric exchange, the connections, interactions, and transfer of interchange of ideologies as well as materials which results from trade can be uncovered. Exchange routes can be reconstructed through first identifying and then sourcing the materials, then determining how materials from these sources were distributed, utilizing this as evidence of communication networks between communities.
