About us

Digital Library Systems and Services (DLSS) supports the mission of SUL by working in collaboration with relevant Stanford University Library units and individuals to:

  • plan, design, implement, and operate technology services, systems, and infrastructure for the Stanford University Libraries, including the library online catalog (SearchWorks) and component parts; web and access systems, digitization lab software (labware); and the core server, database, storage, backup and web infrastructure.
  • provision and manage digital resources for the Libraries through their complete lifecycle, including project management and digitization/preservation consulting; acquisition; digitization; data modeling and technical metadata design, specification, and generation; digital preservation; online access; and overall management of digital materials.
  • research, evaluate, design, and implement emerging technology, standards and methodologies for digital collection development and management, digital preservation (including the Stanford Digital Repository), online access to library resources, and the related library infrastructure to support all of the above.

DLSS builds upon purchased systems, locally developed tools, and increasingly, public domain software. For each of these, DLSS provides significant local integration and enhancement, plus ongoing support of these applications and their technical environments. The group also actively participates in and contributes to the library, higher education and open source communities around technologies, methods, and standards.

DLSS leadership

Tom Cramer. Associate University Librarian and Director of Digital Library Systems and Services
Tom oversees the development and implementation of Stanford’s digital library services for digitization, discovery, delivery, preservation, and management of digital resources that support teaching, learning, and research. Tom directs the Stanford Digital Repository, the development of SearchWorks, and the Libraries' technical approach to its linked data infrastructure.

Hannah Frost. Assistant Director, Digital Library Services
Hannah directs the Libraries' digitization services (across all formats) and also leads a team of product and service managers (PSM). The PSM team focuses on defining and delivering solutions to users inside and out of the Libraries that support the creation, curation, publication, preservation, and use of digital content for teaching and research at Stanford. She is keenly interested in the unique challenges of media preservation and increasingly motivated to make digital collections available as data for computational access at scale.

Mark A. Matienzo. Assistant Director for Digital Strategy and Access
Mark leads the digital library discovery, access, and delivery portfolio for Stanford Libraries, and manages a team of software engineers and user experience designers that develop and maintain these systems. Mark also provides strategic and technical leadership for collaborative digital library projects undertaken by Stanford Libraries with both internal and external partners.

Thib Guichert-Callin, Acting Program Manager, LOCKSS
Thib manages the provision of distributed digital preservation software and services used by more than one hundred institutions across multiple networks, including the Global LOCKSS Network and the CLOCKSS Archive. He brings a deeply technical focus to the brass tacks of long term digital preservation, having served as a long-time software developer on LOCKSS and most recently as the engineering manager for the LOCKSS Program.

Julian M. Morley. Manager, DLSS Operations
Julian leads the operations group, providing core services and infrastructure support to other teams in DLSS and across the libraries. Julian is focused on ensuring that the technologies underpinning all DLSS efforts are secure, performant, scalable and sustainable - whether they are deployed on campus or in the cloud.

Vivian Wong. Associate Director for Infrastructure Engineering
Vivian manages the software team for the Stanford Digital Repository (SDR). Additionally to SDR, she also oversees the development of the thriving Linked Data infrastructure in support of projects such as Sinopia and RIALTO. She collaborates with other DLSS groups in developing the department-wide engineering process. Her experience prior to Stanford was focused on building software for the scalable and efficient SaaS environments, delivering robust solutions for the TV and embedded markets. Customer-first is her mantra.
