This document, produced for the Arts and Humanities Data Service (AHDS) of Great Britain, offers detailed guidelines for the creation and maintenance of digital archives for archaeological projects. Among other things, the authors offer a comprehensive definition of digital archiving, discuss good digital archiving practices, and consider mechanisms for the creation of a national index to digital archives in archaeology. While the Guide is specifically written to address archaeological practice in the United Kingdom, many of its recommendations have universal applicability. The document is best considered in tandem with other documents from the Archaeology Data Service (see the September 22, 1998 Scout Report), such as its Survey of User Needs of Digital Data and Guidelines for Depositors.
