Requirements and Options for the Digitization of the Illustration Collections of the National Museum of Natural History

This report, sponsored by the National Museum of Natural History's Collections and Research Information System (CRIS) Development Program, is the result of a study to understand the requirements and alternatives for digital conversion of scientific illustration collections of the Museum. The analysis was undertaken by Mitretek Systems, McLean, Virginia. Specific digitization procedures, methods, and standards are being examined by the Museum within the framework of pilot projects to test the initial recommendations contained in this report.

Comparison of Computer Image Analysis and Physical Analysis of Artifacts

"Abstract: Archaeological visualization can be valuable to archaeologists if it includes analytical possibilities and solutions to methodological problems that confront them (e.g., faster data sharing). In this study of methods, non-metric and metric analyses were carried out on images (taken using a digital camera) of 8 two-dimensional views of each of 30 projectile points. Metric analysis included the invention of programs that produce grids as measuring devices that adjust to the length of a centimeter scale in an image. Portability of data and speed of data communication are explored in this project, especially in the creation of this website because the data can be shared very quickly with other archaeologists, and the project can be transferred somewhat easily to a CD-ROM to avoid problems associated with obtaining the information from the internet (e.g., slow connections). Issues associated with the use of these statistically valid results are also discussed."

Stanford University
The Digital Michelangelo Project

"Recent improvements in laser rangefinder technology, together with algorithms developed at Stanford for combining multiple range and color images, allow us to reliably and accurately digitize the external shape and surface characteristics of many physical objects. Examples include machine parts, cultural artifacts, and design models for the manufacturing, moviemaking, and video game industries.

"As an application of this technology, a team of 30 faculty, staff, and students from Stanford University and the University of Washington spent the 1998-99 academic year in Italy scanning the sculptures and architecture of Michelangelo. As a side project, we also scanned 1,163 fragments of the Forma Urbis Romae, a giant marble map of ancient Rome. We are currently back in the United States processing the data we acquired. Our goal is to produce a set of 3D computer models - one for each statue, architectural setting, and map fragment we scanned - and to make these models available to scholars worldwide."

Includes a ultraviolet fluorescence map"> of Michelangelo's David.

"Once mapped onto our 3D computer model, this data will show the location of waxes and other organic materials that have been applied to the statue over the centuries. Conservators can use this information when planning future cleanings and restorations of the statue."

"Examine[s] the material aspects of three early Netherlandish paintings using digital imaging techniques? From the Introduction:

Computers and new imaging technologies are fast becoming an integral part of the work of conservation. Conservators and scientists in the Straus Center for Conservation, located in the Fogg Art Museum, have been at the forefront of research into these technologies.
This interactive program demonstrates the ways in which computer technology can be harnessed to add to our knowledge about Renaissance paintings and how they were made.

The multi-faceted and precedent setting role which conservation plays in digital image conversion projects in the NDL in the areas of consultation, training, and treatment for scanning is discussed. Additional information will be added in the coming months which will provide details regarding experience with specific collections."

Final Report of the Library of Congress Manuscript Digitization Demonstration Project - October 1998

"This project explored the digitization of large-scale twentieth-century manuscript collections by producing images of 10,000 document pages, mostly typescripts, from the New Deal Federal Theatre collection. The project was sponsored by the Library of Congress Preservation Directorate, overseen by the National Digital Library Program, and carried out from 1994-97 by Picture Elements, Inc.

Proceedings of the Workshop on Electronic Texts - June 1992

This workshop, held at the Library of Congress, brought together many of the pioneers in electronic text and document imaging in library or archives contexts. In part, the meeting highlighted the differences in motivation and approach between those who focussed on searchable text marked up with SGML and those concerned with imaging as a part of library preservation."
