On its face, the University of Texas Libraries looks like any other modern academic library system: students queuing at printers, study groups in the Perry-Castañeda Library, books circulating in and out. But behind the scenes, in basements, labs and high-density storage facilities across Austin, a quieter scene plays out.

It’s the race against time.

Paper yellows, bindings crack, videotape degrades and digital files disappear from obsolete media. The very materials that help make The University of Texas at Austin a world-class research institution are fragile. Without constant care and attention, they could be lost.

The university’s institutional landscape of collections is exceptional: more than 170 million objects and specimens are distributed across some forty units, including rare books, geological cores, biological specimens, architectural drawings, sound recordings and more. These holdings sprawl across an entire campus ecosystem – original manuscripts, photographs and the Gutenberg Bible at the Ransom Center, modern art at the Blanton Museum, historical archives at the Briscoe Center, even geological cores and frozen genetic samples housed in scientific labs. Together, they rival the Smithsonian in size and diversity.

That scale is both a triumph and a challenge. Many of these materials are environmentally sensitive, and were never designed to last for centuries. Without deliberate preservation strategies, they will decay, fade or slip into obsolescence as new technologies supplant older ones.

The breadth of resources at the university is extraordinary, and it comes with daunting preservation needs. Each type of collection – artworks, specimens, maps, recordings – requires different expertise and different infrastructure to maintain.

Within this vast ecosystem of treasures, the University of Texas Libraries plays a critical role – stewarding the core scholarly resources that fuel teaching and research. With more than 10 million volumes, including special collections like the Nettie Lee Benson Latin American Collection and the Alexander Architectural Archives, the Libraries form both a foundation and a showcase for the University’s research mission.

These collections are heavily used, widely accessed and globally significant. Their preservation is not optional – it is an imperative tied directly to the university’s role as a leading public research institution, and steward of public resources.

When students pick up a library book or access a digitized resource online, they rarely recognize the imperceptible scaffolding keeping that resource alive. But at the Libraries, preservation is not a luxury – it’s a fundamental responsibility and a central tenet of its mission. The Libraries’ holdings span not only traditional print, manuscript and audiovisual collections, but vast, heterogeneous, digitized and born-digital records that present new and unexpected challenges. The preservation of physical artifacts and the ongoing stewardship of digital materials must work in tandem if the university is to continue to thrive as a living archive.

In the Preservation and Digital Stewardship unit at the PCL, staff mend spines, stabilize brittle paper and digitize fragile items to reduce handling. Items requiring specialized treatment are routed through the Campus Conservation Initiative to conservators at the Ransom Center, where advanced equipment and techniques can extend their life. It’s a story of triage, teamwork and unseen craftsmanship.  If physical preservation is a battle with chemistry and physics, digital preservation is a battle with code. Files don’t yellow or fray; they disappear silently – lost to corrupted disks, unsupported formats or vanishing software.

The Libraries’ Preservation & Digital Stewardship unit is the frontline defense. Staff recover files from obsolete media like floppy disks and Zip drives, build redundant storage systems, and create metadata that ensures digital objects remain usable as technologies change. They work hand-in-hand with repositories like the Alexander Architectural Archives and the Benson Latin American Collection to integrate preservation practices into projects from day one.

“We allocate resources to preserve our collections, both physical and digital, so that they will remain accessible for researchers far into the future,” says Wendy Martin, Assistant Director of Stewardship.

“Our collections contain a wide variety of formats. We have a very long history of caring for the traditional analog materials found in libraries,” Martin explains. “It is important that we take the same care in ensuring that our digital collections will remain accessible for the long term, as well. The methods are different, but the principles are the same.”

In line with emerging best practices across research libraries, the Libraires also employs tools that identify preservation risks across massive digital collections. These allow staff to spot which file formats are endangered, which collections are most vulnerable, and where to intervene first. Preservation, in this new paradigm, is proactive, data-driven and strategic.

Scale compounds the challenge. Each year, the Libraries acquire tens of thousands of volumes – nearly a mile of shelf space annually. With no new stacks built on campus, UT relies on a high-density storage facility in North Austin – at the J.J. Pickle Research Campus – where low temperature and humidity conditions dramatically slow deterioration.

In those warehouse-like aisles of high shelving, preservation is less about heroics than about patience and planning. Proper conditions mean a book or box of negatives might be able to sit stable for decades (or even centuries) waiting for its moment of rediscovery.

“Harvard University built the first offsite high-density library storage facility in 1986, with materials shelved by size on densely-packed shelving, with low and stable temperature and relative humidity,” explains Martin. “The University Texas was an early adopter of this now prevalent model, building our first module in 1993. Preservation-quality storage of this type allows us to retain materials for the long term, while making space on our shelves for new acquisitions.”

The Libraries are currently in the completion phase of an expansion of the Pickle campus storage facility, expected to open in early 2026. The new unit is the third addition to the complex, and represents and evolutionary step in its overall development. The Collections Preservation and Research Complex will feature new new low-bay cool and cold environments ideal for materials like film, photographs, textiles, and artifacts, significantly benefitting partners like the Harry Ransom Center and the Briscoe Center for American History, along with specialized workspaces for conservation, digitization, and collection care, as well as a shared reading room that will allow researchers to consult materials directly at the CPRC, reducing turnaround times and minimizing transport risks for fragile items.

The preservation mission on campus isn’t happening in isolation. The Association of Research Libraries (ARL), of which the Libraries is a member, has long declared preservation an “enduring responsibility” for research libraries. ARL emphasizes that enduring access to scholarship requires both strong local programs and cooperative efforts across institutions.

Reports like ARL’s New Roles for New Times argue that preservation today is not just about repair, but about digital curation – lifecycle planning, collaborative storage, metadata standards, and new skill sets for library staff. Other studies, such as Safeguarding Collections at the Dawn of the 21st Century, highlight the need for comprehensive strategies that integrate physical, digital, and legal aspects of preservation.

The Libraries’ work mirrors these evolving norms. Its blend of physical conservation, digital stewardship, climate-controlled storage and forward-looking policies places the Libraries squarely within the network of research libraries redefining preservation for the 21st century.

Ultimately, these preservation efforts are about more than keeping objects intact – they’re about maintaining continuity of knowledge. A fragile field recording of an Indigenous language, a digitized map of a vanished city, a frozen sample of an extinct amphibian – all are held not only for current scholars, but “in trust for future generations.”

That trust is both a privilege and a consequential responsibility. It requires resources, policy, collaboration and a relentless commitment to access. And it depends on the quiet, often hidden work of preservation staff whose labor sustains the university’s intellectual and cultural legacy.

Preservation is rarely glamorous. It doesn’t draw ribbon-cuttings or fill stadiums. Yet so many acts of discovery on the Forty Acres depend on it.

Whether it’s a historian uncovering an unpublished manuscript in an archive, or a student discovery of our prehistoric past in a collection of fossils, or a scientific analysis of geologic samples that reveals potential new energy resources, each discovery depends on the quiet, meticulous work of preserving and stewarding the university’s vast collections.

“Preservation at UT Libraries, is a vital thread in the fabric of the university’s mission,” explains Director of Discovery and Access Jennifer Lee. “We’re safeguarding the intellectual and cultural legacy that fuels discovery, learning and the pursuit of knowledge now and into the future.”

For the University of Texas Libraries, and for the broader community of research libraries, preservation is not an afterthought. It is the very heart of the mission: to ensure that the past remains as accessible, complete and meaningful as possible – for today, and for generations to come.
