The World Wide Web gives us an unprecedented opportunity to provide people around the globe with access to significant historical and cultural works. However, the Web, by its very nature, requires those works to be in some electronically transmittable form before they can be made available, and most historical documents, by their very nature, are in a form well-removed from the computerized world of today. So how can this gap be bridged? And once a bridge is built, how can we be assured that it will stand over the decades and centuries to come? Moving Theory into Practice: Digital Imaging Tutorial, published by the Cornell University Library Department of Preservation and Conservation, provides a comprehensive overview of the issues involved in translating photos and documents into electronic form. This online tutorial explains the various steps, the technology behind them and some of the organizational challenges that they present. This publication provides easily-accessible information that should be of increasing interest to anyone involved with digital publication and archiving of existing works.
