The future is uncertain. Academic institutions require that key aspects of their scholarly histories, heritage and research remain part of the record of human endeavor in spite of, or perhaps because of, whatever will happen next. As an emblematic part of institutional identity, the potential loss of core online academic collections that are part of what an institution means could be catastrophic. Oral history collections, born digital artworks, historic journals, theses, dissertations, media and fragile digitizations of ancient documents and antiquities are examples of irreplaceable resources. What happens if a strategic institutional collection is lost? Will a critical building block of knowledge be lost forever? It is essential for scholars of the future that action is taken now to protect digital assets that are at risk of loss.
DPN ensures the secure preservation of stored content by leveraging a heterogeneous network that spans diverse geographic, technical, and institutional environments. DPN’s preservation process can be expressed in five steps: (1) Content is deposited into the system via an Ingest Node; (2) Content is replicated to at least two other Replicating Nodes and stored in varied repository infrastructures; (3) Content is checked via bit auditing and repair services to ensure the content remains the same over time; (4) destroyed or corrupted content is restored by DPN; (5) as Nodes enter and leave DPN, preserved content is redistributed to maintain the continuity of preservation services into the far-future.
The DPN federation is comprised of geographically separated repositories that are built upon different underlying system architectures. These repositories act as Nodes on the DPN network and function either to ingest and store content or to replicate and store content. The Nodes work in concert to ensure that the digital content is secure and that the objects are preserved.
The DPN launch features five Nodes, each with specific offerings as Ingest and Replicating Nodes:
DPN is a member-driven organization and is dependent on the collective expertise of digital preservation experts, technical leaders, metadata experts, legal experts and other leaders throughout higher education. DPN Members work on the thorny issues that are inherent in the development of a digital preservation system built to last beyond technological change, organizational change or system failures. Through this collaboration DPN is built to withstand catastrophe on many levels in order to secure the most valuable digital content for future scholars and researchers.
DPN operates as an independent organization under the umbrella of the not-for-profit organization Internet 2 - a community of international leaders in research, academia, industry, and government - who collaborate on the adoption of innovative technologies.
DuraSpace, an independent not-for-profit organization that provides leadership and innovation for open technologies, worked with Chronopolis to develop an ingest portal for DPN. DuraSpace collaborates with the academic, scientific, cultural, and technology communities by supporting projects and creating services to help ensure that current and future generations have access to digital heritage materials.
As a part of DPN membership members may deposit 5TB of digital content for no extra cost. Additional TB may be purchased if desired. This content will be replicated so that there are three copies of the content in the system in various locations around the country. The DPN nodes utilize community approved best practices and the system is designed so that the content is checked for fixity (and repaired should problems be detected) at least once every two years. DPN members can be confident that content in the system is well protected for the long term.
What sets DPN apart from other repository solutions is the business model that provides long-term support of deposited content upon deposit. Members pay a membership fee that allows for deposit of up to 5TB of content annually. Should members decide that they could no longer participate for any reason (including failure of their institution) the content remains protected in the DPN system for the long term. The deposit agreements that are signed upon deposit of the content specify that members can choose to pass along the deposited content to another party should an institution decide that it can no longer maintain custody. These agreements and the business model support the succession of the content for future scholars.
The DPN system was developed by the support of membership fees paid by the 60+ DPN Charter Members. Those Charter Members pay an annual membership fee of $20,000 and they may deposit up to 5TB annually as a part of their membership. The Membership Committee and the Pricing Committee are currently examining other types of memberships to accommodate the needs of library consortia, research data consortia, smaller institutions who have less content than 5TB and institutions who have content to deposit that far exceeds 5TB. We feel that it is important to have a model that supports all kinds of institutions that have unique and valuable content that must be passed forward to future scholars.

In 1964, Pulitzer Prize-winning author and poet Robert Penn Warren conducted a series of oral history interviews with prominent leaders of the unfolding Civil Rights Movement. Warren, who was born in Guthrie, Kentucky, grew up in a segregated South. These interviews were conducted while researching his book Who Speaks for the Negro published in 1965, representing his personal intellectual transition on the topic of segregation. Warren recorded interviews with over 40 leaders including Martin Luther King Jr., Malcolm X, James Baldwin, Kenneth Clark, Adam Clayton Powell, James Forman, Roy Wilkins, Claire Harvey, Stokely Carmichael, Bayard Rustin, and Vernon Jordan.
As an interviewer, Warren spends very little time at the superficial level. Soon after pressing record, Warren quickly asks the interviewees to engage in dynamic, critical and philosophical discussion and inquiry. He does not hesitate to ask Martin Luther King Jr. about Malcolm X and ask Malcolm X about Martin Luther King Jr. These interviews are not simply narrations and remembrances about the past. They represent a critical engagement with the present and a deep envisioning process for the future.
When the Nunn Center developed their innovative OHMS search / synchronization system for online interviews in 2008, the Robert Penn Warren Civil Rights Oral History Collection was one of the first oral history collections to be made accessible. With this powerful system, an archival collection that may have been used dozens of times over a period of decades, is accessible in cutting-edge fashion, and used thousands of times by students, researchers, and teachers all over the world.
The fully searchable and synchronized interviews from the Robert Penn Warren Civil Rights Oral History Project can be accessed online via SPOKEdb, the Nunn Center’s online repository. There are very few primary sources from this time period that reflect so directly, critically and personally on the Civil Rights Movement as does this collection of oral history interviews. In Warren’s December 23, 1964, gift letter to the University of Kentucky Libraries, Warren states “This collection is unique, it would seem, for the interviews are very long and ‘in depth,’ not at all like the ordinary newspaper and magazine thing…. This, it would seem, is significant research material.” As a result, when tasked with identifying Nunn Center oral history collections for our first collaboration with DPN, Warren’s interviews with leaders of the Civil Rights Movement was one of our obvious first choices. These interviews, indeed, represent “significant research material.”

Imagine going into the basement of the old Physics Building on the University of Iowa campus and discovering data tapes in cans that had begun to mold. Upon closer examination, the tapes were determined to be the first data transmitted from space that eventually led physicist James Van Allen and his team of graduate students to discover the existence of radiation belts around the earth - the Van Allen belts. The existence of these radiation belts led to a remapping of the solar system.
These original data tapes from the Explorer and other early space missions had been stored for decades in an abandoned particle accelerator chamber in the basement of the 1910 Physics Building. It wasn’t until the big flood of 2008 that the degradation of the tapes was noticed. At that time, the physics department and the University of Iowa Libraries launched a rescue and restore mission to preserve and digitize the 694 tapes from America’s first satellite mission, Explorer 1.
To the untrained ear the tapes don’t sound like much more than white noise, but to James Van Allen and his team, the gaps in the tapes led them to conclude that space was radioactive. Among other things, this key finding led NASA to redirect the trajectories of space flights in order to minimize astronauts’ exposure to unnecessary levels of radiation.
These tapes document a fundamental discovery about our solar system that has been important to generations of scientists. Preserving the digitized content of the tapes in DPN, to ensure access for future generations of scholars, was an easy decision for Daniel Johnson, Digital Preservation Librarian at the University of Iowa Libraries. You can read about the origin of the tapes, their research significance, and their historical significance at this link. You may also click here to listen to a brief conversation between Daniel Johnson and Mary Molinaro, DPN Chief Operating Officer, about this special deposit of the digital data into DPN.
Since 2005, Texas Tech University (TTU) Libraries have been digitizing content for long-term preservation. Among the many collections that have been scanned, the most notable are 14,000+ theses and dissertations spanning the entire history of the university. This digitized and born-digital content represents Texas Tech’s unique intellectual output and its greatest contribution to the scholarly record.
Several years ago when the Libraries joined DPN (as a consortial member via the Texas Digital Library), they also hired a Digital Stewardship Librarian to organize and preserve the collections, as well as help make policy decisions about the future of the collections’ curation. With the increasing size of collections and the associated costs for preservation, the need to identify and prioritize collections for preserving is crucial. The option of saving everything is simply not feasible.
TTU’s Digital Stewardship Librarian has created a preservation policy in which different kinds of materials receive appropriate levels of digital preservation. Reviewing and identifying the unique digital items that TTU Libraries possesses allows them to appropriately prioritize the items requiring full digital preservation.
Although the review process necessitates an investment of time and effort, it yields significant benefits with long-term efficiencies. One such benefit is that TTU’s graduate theses and dissertations are certain to be preserved for future generations.
