About the CTDA

The Connecticut Digital Archive (CTDA) is a collaborative effort of the Archives & Special Collections at the University of Connecticut Libraries and the Connecticut State Library. The CTDA is dedicated to the maintenance, delivery, and preservation of a wide-range of digital resources for educational and cultural institutions and state agencies in the State of Connecticut.


The mission of the CTDA is to provide services for the preservation of and access to digital assets inherent to the research, information, and educational missions of its participating institutions.


The vision of the CTDA is to serve as a standards-based repository and infrastructure supporting a diverse set of applications, services, and discovery tools that offer long-term management, secure storage, preservation solutions, and – whenever possible- open access to digital assets of enduring value, as determined by the CTDA participants.

Organization and Governance

The Connecticut Digital Archive (CTDA) is a service of the University of Connecticut Libraries. The CTDA provides services to preserve and make available digital assets related to Connecticut and created by Connecticut-based, not-for-profit educational, cultural, and historical institutions, including libraries, archives, galleries, and museums. In order to insure that the needs of the community are being met by CTDA services, the UConn Libraries convenes committees to provide strategic advice on CTDA operations and services.

The CTDA Advisory Committee is made up of colleagues and peers from the cultural heritage, digital preservation, and academic communities in Connecticut and represents a wide variety of talents, knowledge, and perspectives. The committee meets quarterly to share experiences and provide advice on CTDA services and programs. To learn about membership, members, meeting dates, agendas, and minutes, visit our CTDA Advisory Committee page.

Sustaining Digital Cultural Heritage in Connecticut

In the late 1990s a group of forward-thinking individuals acting according to a vision to “facilitate access to digitized primary sources about Connecticut and foster digital stewardship among Connecticut cultural institutions” created Connecticut History Online. CHO was a pioneering project that made Connecticut a leader in collaborative digital collection building. Given the technology of the time and the limitations of its resources, CHO succeeded admirably in supporting both aspects of its mission.

If we were to begin to build CHO today, we would include both the access and stewardship aspects of the original mission, but think of them very differently than we did in 1999. Today, we build topic-based digital portals on large-scale digital preservation repositories, separating the activities of preservation from those of access and presentation. This makes it possible to truly support stewardship over the long term for valuable digital assets (something that the original CHO technology infrastructure could not do) and, through tools that make content and metadata creation and management more accessible to more people, greatly expand the breadth of the content for which we can provide access.

Supporting a new approach to securing the original vision will keep the vision alive, and put digital cultural heritage in Connecticut on a secure foundation well into the future.

The CTDA is dedicated to the maintenance, delivery, and preservation of a wide-range of digital resources for scholars, students and the general public. Operational since November 2013, the CTDA provides preservation digital repository services for educational and cultural organizations and state agencies in Connecticut.

CTDA Community

The CTDA community consists of educational, cultural, and memory institutions based in the state of Connecticut. The three distinct communities of the CTDA are: University of Connecticut, Connecticut State Library, Connecticut based libraries, archives, galleries, museums and other memory institutions. Eligible institutions have a mission to preserve and make available historically valuable resources and records. The CTDA is not open to individuals or organizations that do not have as part of their mission a commitment to preservation and access. The CTDA encourages individuals or non-memory organizations to work with an eligible institution to preserve their organization’s records.

Channels Hosted by the CTDA

The CTDA offers participating institutions the ability to manage their content in an aggregated site at no additional cost for that site. Participating institutions that want a web site (channel) of their own may pay for the CTDA to create and maintain their own channel. The costs of a CTDA channel are set each year in June and are calculated for each channel requested; presentation and management sites are considered separate channels. Institutional Channel services include training for the Institutional Site Administrator and guidance on channel theming.
