Preview Using Computers in Archaeology: Towards Virtual Pasts

USING COMPUTERS IN ARCHAEOLOGY As computing becomes increasingly essential to the work of the archaeologist, archeologists require a clear understanding of the impact of information technology upon their discipline. This non-technical introductory volume discusses and explains the influence of computers on all aspects of archaeological research and interpretation, from survey, excavation and landscape to museums, education and communicating the past. The author meets the need of the archaeologist to keep abreast of how computers can assist at all stages of archaeological research and data analysis. Theoretical information, focusing on Geographical Information Systems, for example, is presented through description of archaeological processes, and is consistently practical and free from jargon. The author acknowledges the problem of obsolescence in computing and presents archaeological technology as an on-going, constantly changing process rather than as a final, achievable state. The book will thus remain relevant through future advances in technology and informative about the general principles of, and the issues arising from, the relationship between computers and archaeology. Highly illustrated and referenced throughout with case-studies and examples, Using Computers in Archaeology: Towards Virtual Pasts is a timely survey of this increasingly important area of archaeology, catering for both the student and the experienced archaeologist. Gary Lock is Lecturer in Archaeology at the University of Oxford, editor of Beyond the Map: Archaeology and Spatial Technologies (2000) and co-editor of On the Theory and Practice of Archaeological Computing (2000).
