Digital Training Workshops:
Use of Digital Image Technology for Preservation and Access
Cornell University, Ithaca, New York
June 12-16, 1995
August 14-18, 1995
October 9-13, 1995
March 18-22, 1996

Organized by Cornell University Department of Preservation and
Conservation, co-sponsored by the Commission on Preservation and Access.

The Cornell University Department of Preservation and Conservation
announces its offering of a series of digital training workshops.  The
workshops are designed as intensive one-week training programs to
provide participants with the means to develop a baseline knowledge
about the use of digital image technology for preservation and access.
The training will focus on the reformatting of paper- or film-based
library materials, including books, serials, archives, manuscripts,
graphic materials, and photographs.  Primary emphases will be placed on
the conversion process itself, on an examination of factors affecting
image quality, and on the use of digital imaging in a preservation

Each workshop will combine the practical with the theoretical.
Participants will select samples of materials from their own collections
to bring to Cornell for scanning.  During the workshop, participants
will be introduced to the vocabulary and concepts of digital image
technology, the components of imaging systems and their attendant costs,
factors affecting conversion quality and the longevity of digital
information, and access-related issues.  Through presentations, review
of computer-projected illustrations, hands-on exercises, six hours of
directed lab assignments, demonstrations of current digital projects,
and an extensive training notebook, participants will gain an
understanding of how bitonal, grayscale, and color scanning affect the
capture, storage, and use of a broad range of library materials.

The workshop is intended for preservation administrators, librarians,
archivists, records managers, curators, and other information
professionals who are responsible for collecting, preserving, and making
accessible documentary materials.


Anne R. Kenney and Stephen Chapman will serve as the principal faculty
for these workshops.  They will be joined by several guest instructors,
including James Reilly who will present a session on digital conversion
of photographic materials.

Anne R. Kenney is the Associate Director of the Department of
Preservation and Conservation at Cornell.  For the past five years,
Kenney has managed and co-managed the majority of Cornell's digital
imaging projects.  She also developed the New York State digital
training workshop concept and served as one of the principal instructors
in that series.  Kenney is the past president of the Society of American
Archivists, and serves as one of two American representatives to the
Committee on Image Technology of the International Council on Archives.

Stephen Chapman is the New York State Preservation Intern (through March
1995) in the Cornell University Department of Preservation and
Conservation.  Chapman is the project liaison for the NEH-funded
"Digital to Microfilm Conversion Project" and was an instructor in the
New York State digital training series. He has co-authored with Anne R.
Kenney the tutorial, "Digital Resolution Requirements for Replacing
Text-Based Material: Methods for Benchmarking Image Quality", to be
published by the Commission on Preservation and Access in the spring of

James Reilly, Director, Image Permanence Institute, has been designing,
executing, and directing research into photographic preservation since
1978.  He most recently participated in the RLG Technical Images Test
Project, which investigated how various choices in capture, display,
compression, and output affect image quality for photographic materials.

Institutional Profile: Since 1990, Cornell has been investigating the
use of digital image technology for preservation and access.  With
private, public, and corporate support, the Department of Preservation
and Conservation has undertaken a series of projects to digitize
research library materials and to produce high quality paper and
microfilm replacements.  The projects also assessed the role of digital
technology in providing networked access to library and archival
