The Long View: Protecting the Past for the Future

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.

A Space Solution in the Distance

Texas may pride itself in being big, but as anyone around the Forty Acres these days knows, that “bigness” is finite.

Back in the early 1990s, as Austin was hitting its stride in terms of growth with the arrival of tech industry and the nascent popularity of the city as a destination, forward-thinking minds at the University of Texas Libraries recognized that the ever-expanding physical collections — which at the time had reached in excess of 6 million books — couldn’t forever be contained on a rapidly growing campus.

To avoid what they saw as a future crisis for the preservation and accessibility of the collections, the Libraries sought and received approval and funding to construct a library facility based on the Harvard Depository — a preservation facility that had been developed at Harvard University in 1986. The goal was to relocate low circulation items into a highly controlled environment with optimal preservation conditions, coupled with a retrieval process to get items back into the hands of users should they be needed.

Sensibly referred to as the “Harvard Model” — which has become a standard for materials preservation — the building layout for the Library Storage Facility (or LSF as it’s known within the Libraries lexicon) is an interconnected structure of generational  units situated on the lonely south side of the university’s satellite Pickle Research Campus on a close-cropped berm of desiccated weeds in far north Austin with downtown only barely visible in the distance. The vertically-oriented concrete panel edifice is stark and brutalist, an almost unwitting tribute to its campus counterpart, the Perry-Castañeda Library, a likewise imposing monolith and arrival hub for most of the materials that are retrieved from storage.

The storage structure itself is actually a series of separate construction projects that spanned several years. The first unit was opened in 1993, the second in 2009 and the third, LSF 3, opened late in 2017 and is currently being filled with library materials.

Each section of the building accommodates 30-ft tall shelving units in a series of aisles and each shelf section (called a “ladder”) is a designated height to fit volumes of like format and size — an almost profane violation of standard library organizational protocols — thereby ensuring the most efficient application of available space. Shelves are accessed via a “picker,” a specially-designed forklift that can be controlled from a spanning basket that can reach the very highest level of the structure.

Everything in the facility is systematically barcoded — the item, the storage tray in which it sits, the shelf on which the tray sits — and that information is stored and managed in an inventory control systems that allows staff to quickly and easily locate any of the 2 million items stored at LSF.

The Library Storage Facility is managed by the Libraries, but additionally serves as preservation storage for collections from the Dolph Briscoe Center for American History, the Harry Ransom Center and the Tarlton Law Library. LSF 2 was even built in part with support from our siblings and rivals down the road at College Station, and as a result, the A&M Libraries have a dedicated aisle of space for materials mingling with the resources of the Longhorn Nation.

Another similar project at A&M’s Riverside campus — the Joint Library Facility — was  constructed as a collaboration between the Texas A&M System and the University of Texas System allowing for the storage of widely-held, but infrequently used, items materials across Texas academic institutions. The nature of this facility offers participating libraries the opportunity to pare down some of their materials to a single copy that is then collaboratively stored and served from this shared facility.

Collectively these storage facilities have facilitated substantial growth in Libraries holdings — which now stands at more than 10 million items — by allowing for the transferral of low-use items from overstretched campus locations to the high-density facility at the Pickle Research Campus. We still spend over $1.5 million per  year on traditional physical resources – even as the Libraries moves to incorporate the ever growing array of electronic information resources – and we expect this practice to continue for the foreseeable future.

Professional stewardship of library materials is a key part of UTL’s institutional mission.  The conditions at LSF are closely controlled to create the best environment for the long-term preservation of materials, with efforts to maintain a temperature of 55°F and relative humidity at 35%. These conditions significantly slow the deterioration of paper, inhibit the growth of mold, and reduce the likelihood of insect infestations. “With the conditions maintained at the facility, you could basically put an item into storage and come back 240 years later to find it in a stable state,” says Ben Rodriguez, who manages the library storage facility. Rodriguez oversees a team of library specialists who help to develop processes and run the day-to-day operations of LSF with the assistance of ten student workers.

“The stability of conditions at LSF reduces the mechanical wear-and-tear that would otherwise occur as paper and leather expand and contract with the changes to humidity levels in a library environment,” says Wendy Martin, assistant director of stewardship. Martin oversees the preservation efforts — both physical and digital — for the Libraries. “Library materials stored in ideal conditions will have a much longer lifespan than materials stored in open stacks space designed for human comfort.”

Beyond the space-saving functionality of library storage facilities like these, there is a compelling financial reason for moving low-use items off-site.  A 2010 study showed the cost of storing a single volume in an open library stacks facility is $4.26 per year, taking into account personnel, lighting, maintenance and heating and cooling costs. The cost is pegged at 86 cents per volume for storage at a facility such as the Riverside unit jointly operated by the Texas A&M and University of Texas Systems — representing a savings of $3.40 per volume.

Off-site storage has also allowed the Libraries to respond to changing the changing needs of faculty and students by redesigning some of our library spaces to accommodate collaborative study and new technology resources that help to better prepare library users for transition to a 21st Century economy. As the library evolves from a storehouse for information into a platform for innovation and creating new knowledge, having the option to reimagine spaces to meet the changing expectations of the public enhances the library’s relevancy.

Of course, none of this storage would mean very much, though, if the Libraries weren’t also constantly working to improve both the efficiency of access to materials that are selected for housing at LSF, and the selection process itself. Recently, with support from Provost Maurie McInnis, an additional full-time driver and transport vehicle were added for the sole purpose of improving turnaround times for material requested from LSF. Beginning in the fall this driver will make a second daily transportation run between LSF and the main campus. This means patrons can expect to receive email notification of an item being ready for pickup within one business day of their initial request. With the Provost’s support we were also able to hire an additional staff member at LSF, providing the necessary staffing capacity to pull materials for delivery twice daily.

Libraries’ subject liaisons work on a daily basis with university faculty and researchers to build collections that support the University’s teaching, learning, and research mission, in both core and emerging disciplines. The undulations of academic and research focus at UT are the subject of constant analysis by library professionals that, combined with specific requests from our users and a robust set of circulation data, help the Libraries make decisions regarding the placement of collections on campus. This is all to say that when decisions are made to take materials from the shelves, it’s not done lightly or without careful consideration. In light of recent concerns about how decisions are made regarding the transfer of materials to storage, the Libraries has redoubled its effort by tasking a cross-functional team with reviewing and improving the decision-making process for relocating resources.

The ultimate goal of having library storage facilities is to continue to grow our collections resources while adapting the way libraries function to meet the needs of modern users. First and foremost, we want students and our other users to be productive. But productivity can be measured in different ways. It comes not only from the opportunity of discovering a book on the shelf run that wasn’t the object of your search, but it can also result in the form of the serendipitous discovery that happens when diverse groups of students get together and share ideas. We want to create conditions that will allow different types of learning and discovery to occur.

Plans are already underway for the next module at LSF, which will not only feature more high- density storage, but will also provide some new kinds of spaces for improved preservation and better access to materials stored at the facility. The new construction — to be called the Collections Preservation and Research Complex —will provide storage for three-dimensional objects and ephemera, additional cold storage (40°F) for film, a proper reading room for onsite research, new processing space and a quarantine room.

The Libraries has been building the magnificent collections we have today for over 130 years, and, with a little effort and care, we can continue to not only grow them, but to make sure that they’re here for many, many more years to come.

The Libraries’ Closet

Like so many leather skirts, go-go boots and seersucker jackets that need to be carefully stowed in the interim between their respective periods in vogue, these great buildings of books, too, need to occasionally clear space for more useful, timely purposes.

To that end, the Libraries have thus far accommodated a need for additional “closet space” through the construction of off-site warehouses much reminiscent of the one imagined in the closing scene of Raiders of the Lost Ark, seemingly endless rows of shelving stretched from concrete floor to stories-tall rafter, where once-prized tomes and formerly-current periodicals can reside until such time as they are once again called upon to provide the critical information needed to complete some important research or solve some lingering question.

These library storage facilities (LSFs) house those low-circulation items and fragile materials that might be considered complementary resources for collections from across the campus of The University of Texas at Austin and beyond.  Both the Harry Ransom Center and the Briscoe Center for American History are reliant upon this remote storage in order to free up room for the more high-value, high-use items in their ever-growing collections of cultural artifacts. Likewise, as parts of the Libraries’ valuable print collection are accessed less frequently than in the past, it’s logical to move those volumes into a high-quality storage environment and establish systems for retrieving books as scholars request them from storage. The migration creates space that can be repurposed for student use and newer technologies to facilitate a more productive, modern learning environment.

The Libraries also enjoined sibling rivals at College Station in two of the ventures thus far — the second of two facilities at the Pickle Research campus in North Austin, and a joint library facility (JLF) at Texas A&M’s Riverside campus outside of Bryan, Texas. In a collaboration that seeks to minimize the physical presence of materials while still availing the needs of institutions across the state, UT and A&M have pared some of their collections to a single-copy that is then shared cross-organizationally through a delivery system coordinated by the principals. The Austin unit constructed in 2010 is already at capacity, and the Riverside unit, which opened in 2013, has incorporated nearly half a million volumes to date. Given the successful outcomes of the partnership, there are already considerations for the development of further partnerships.

Beyond the space-saving functionality of the LSFs, there is a compelling financial reason for moving low-use items off-site.  A 2010 study showed the cost of storing a single volume in an open library stacks facility is $4.26 per year, taking into account personnel, lighting, maintenance and heating and cooling costs. The cost is pegged at 86 cents per volume for storage at a facility such as the Riverside unit jointly operated by the Texas A&M and University of Texas Systems — representing a savings of $3.40 per volume.

The Libraries learned recently that it had received approval from the Board of Regents to begin construction on a third unit at the Pickle campus, which is necessitated by the Dell Medical School’s future plans to build where the Collections Deposit Library currently stands. CDL has long served as a storage facility on campus for permanent collections, as well as a holding space for unprocessed materials, but due to its age and lack of available space, the building has just about outlived its utility. The new construction at the north Austin campus will allow significant additional materials from other campus locations, as well.

The coming facility will, like its predecessors, be climate controlled, and will hold roughly one million additional volumes, bringing the Libraries over halfway to completing a stated goal of removing two million books from campus locations to off-site storage. Construction on the $8 million building will begin in 2016 and is expected to open in late summer of 2017.
