Anyone faced with such a project would do well to spend $15 and learn a lot about what is involved, as well as be forewarned about a general lack of standards and rules of thumb related to digital imaging. Major sections include discussions of the original object and its reproduction, assessing image quality, color matching, integrating image and text information, building collections, reproduction rights, and user access. …
