Information Access Seminar

Applied Trustworthy Digital Repositories and Risk Assessment

Friday, September 24, 2021
3:10 pm to 5:00 pm

Leslie Johnston

One of the greatest challenges for any digital collection is the multiplicity of file formats, some of which may be decades old, each of which carries different risks and risk mitigation strategies. The discussion will cover some leading digital preservation risk models, what risks exist that they measure (or not), and what data you need. This will be accompanied by an applied use case from the United States National Archives and Records Administration (NARA) and its Digital Preservation Framework, which includes a holdings profile, a risk analysis matrix, and preservation plans for 550 file format variants.

Leslie Johnston is director of digital preservation at the U.S. National Archives. She has over 25 years of experience in applied research on the preservation of born-digital and digitized cultural heritage objects, and on digital library preservation and discovery system architectures and interfaces.

Her expertise is in the management of digital initiatives in academic and cultural heritage institutions. She has led large-scale initiatives to develop new digital and web-based resources for teaching and learning in an academic research environment, and guided the integration of these resources into organizational use. Through this work she has developed an understanding of both the needs of users and the requirements of libraries for creating and maintaining academic information resources.

For many years she was active in the museum automation community, working for various museums, teaching courses on museum systems, founding the online journal eSpectra, editing the print journal Spectra, and serving on the board of the Museum Computer Network (MCN).
