THE PRESERVATION OF ARCHAEOLOGICAL RECORDS AND PHOTOGRAPHS By Kelli Bacon A THESIS Presented to the Faculty of The Graduate College of the University of Nebraska In Partial Fulfillment of Requirements For the Degree of Master of Arts Major: Anthropology Under the Supervision of Professor LuAnn Wandsnider Lincoln, Nebraska December 2010 THE PRESERVATION OF ARCHAEOLOGICAL RECORDS AND PHOTOGRAPHS Kelli Bacon, M.A. University of Nebraska, 2010 Advisor: LuAnn Wandsnider Substantive and organized research about archaeological records and photograph preservation, especially those written by and for archaeologists, are few. Although the Society for American Archaeology has a code of ethics regarding archaeological records preservation, and the federal government has regulations regarding the care and preservation of federally owned archaeological collections, there is a lack of resources. This is detrimental to archaeology because not all archaeologists, given the maturity of the discipline, understand how important it is to preserve archaeological records and photographs. Without documents and photographs from projects, irreplaceable information is lost. This thesis adds to the existing body of knowledge and is developed from over 10 years of professional research into and observations on the topic. Research shows there are simple and inexpensive ways to preserve archaeological records and photographs for repositories and archaeologists on any budget. iii TABLE OF CONTENTS Abstract................................................................................................................................ii Acknowledgements............................................................................................................vii List of Tables......................................................................................................................ix Chapter 1: Introduction.......................................................................................................1 Definition of an Archaeological Record…..............................................................1 Requirements for Records Preservation…...............................................................3 Thesis Purpose.........................................................................................................4 Chapter Arrangement...............................................................................................5 Chapter 2: Making Accurate and Durable Records............................................................7 Introduction..............................................................................................................7 What to Record........................................................................................................7 Why Accurately Record Information?.....................................................................9 How To Photo-Document Projects........................................................................10 Supplies for Making Documents…………...........................................................12 Conclusion.............................................................................................................14 Chapter 3: Saving Records.................................................................................................15 Introduction............................................................................................................15 A Brief History of Records Preservation...............................................................15 Why Save the Information?...................................................................................16 What to Save After Making Documents................................................................18 How to Promote Records Preservation..................................................................20 iv Conclusion.............................................................................................................21 Chapter 4: Caring for Records..........................................................................................23 Introduction............................................................................................................23 How to Care for Archaeological Records..............................................................23 Macroenvironment v.
