The Connecticut Digital Archive:Preservation and Presentation Services for Academic Libraries in Connecticut
September, 2014
What We Have Seen: Using Primary Resources in Work and
Play
Analog = Non-existent “If it isn’t online, I don’t want it”
Unconnected = Invisible “If I can’t find it online I won’t use it”
Collections = Data “I want things that I can manipulate”
Value = Reusable “I want to do what I want with it”
Storytelling = Visualization “I want to use things in “apps”
Connecticut’s digital cultural & academic heritage:
• Ephemeral
• Fragmented
• Not easily discoverable or reusable
• At risk
The Dilemma of Modern Records
How do we insure that resources that exist in digital form today will
reliably exist and be accessible in the future?

Four “-ity”s of Digital Resources
• Sustainability (Durability, Persistence)
The digital object can be maintained and accessed over
time
• Authenticity (Reliability)
The digital object is reliably true to the original
• Interoperability
The ability of one standards-based object to be used in any
other standards-based system
• Reusability
Objects can be used in ways not related to original purpose
• Digital representations of analog originals
• Born digital objects with no inherent “original “form
• Still Images
• Data Sets
• Documents
• Moving Images
• Complex objects
Digital repositories organize data…
Preservation-quality Digital Repository Services
• Are expensive to build and maintain:
• Require large initial investments in technology infrastructure;
• Require large investments in human resources
• Require large ongoing investments in systems maintenance;
• Require large ongoing investments in feature development;
• Are expensive to purchase:
• No “complete solutions”
• Features/services that are lacking must be added ad-hoc and may
not easily integrate
Shared Digital Repository Services
• Collaborative programs can make it possible for
everyone to share the benefits and the cost of:
• Standards-based management systems
• Large-scale repository storage and preservation
systems
• Negotiated connections to national and international
aggregators
• Shared governance
• While retaining local ownership and control of content
What is the CTDA?
• A service of the University of Connecticut Libraries
• A partnership with the Connecticut State Library
• Preserves, manages, and makes available permanently
valuable cultural data and other records produced and
collected by non-profit educational, cultural, and memory
institutions based in Connecticut
• The service hub in Connecticut for the Digital Public Library
of America

Ownership vs Stewardship
• Organizations retain ownership of all metadata, primary
content objects and derivatives.
• Metadata contributed as a CC0 license
• Content objects and derivatives may have access
restrictions—to master files for example—or be
completely open.
Use Only What You Need:
• Preservation Services
• Management Tools
• Metadata Services
• Presentation Channels
• Aggregation Services
• Reformatting Services
