Digital Preservation at the University of Colorado Boulder Libraries ✼ Scope 
 ✼ Done, To Do and Doing 
 ✼ Key Obstacles Western Roundup May 29, 2015 

Archives, Manuscript & Music “…to collect, preserve and make broadly available original source materials of enduring historical significance. The Archives' goal is to acquire materials on a range of subjects concerning the following principal subject areas: Western Americana, Politics, Labor, Environmentalism and Peace & Justice.” 

Collections in the Library • Regular digitization projects • Digitized to FADGI standards • Output from these efforts constitute bulk of digital data 

Research and other campus data • Ongoing efforts and groups to create a research data repository centered at the Library • Other data: • CU Scholar (institutional repository) • Older student theses • University records • Purchased content: e-journals, datasets, etc. 

110 Terabytes presently, and many more terabytes to come. 

What we’ve done • Digital Media Archiving Lab • Remote server backup with RAID5 hard disk redundancy and two tape backup copies off-site • PetaLibrary, NSF subsidized data storage managed through Research Computing group • BagIt for server deposits • File naming & folder organization policies for the servers 

Still to do • Centralized digital object management solution for internal control • Top candidates: Archivematica and DSpace • Storage infrastructure not centered on “the backup” • Infrastructure centered on OAIS technical functions and policy 

What we’re doing now • Digital Archive Task Force to recommend and manage centralized digital object management platform • Profiles of existing storage infrastructures (local library servers and PetaLibrary research data repository) • Profile criteria based off: Requirements for digital preservation system: A Bottom-up approach (2005) by Rosenthal, Robertson, Lipkis, Reich & Morabito. • Advocacy in relevant campus groups and Library management 

Key obstacles • Preservation as derived demand: little interest in it per se, but many keen on what derives from it — future access (and retention of cultural or intellectual capital) ▶︎ • Everyone benefits from digital preservation, but few identify as key stakeholders in the activity ▶︎ Sustainable economics for a digital planet: Ensuring long-term access to digital information (2010) 

Key obstacles • Invoking authority or applicability of external sources — OAIS, PREMIS, NDSA, etc. • Framing the work of digital preservation outside of the strictly technical
