What is APTrust?

The Academic Preservation Trust (APTrust) is a consortium of higher education institutions committed to providing both a preservation repository for digital content and collaboratively developed services related to that content.  The APTrust repository accepts digital materials in all formats from member institutions, and provides redundant storage in the cloud.  It is managed and operated by the University of Virginia and is both a deposit location and a replicating node for the Digital Preservation Network (DPN). The APTrust consortium leverages the expertise of its members to identify and articulate needs for the digital content environment, to prioritize service development, and to collaboratively build solutions.  This approach generates economies of scale and increases value for all members.

Membership and Staff

The Academic Preservation Trust seeks to add members who are interested in participating in building the consortium’s infrastructure, including governance and operations. Institutional members are encouraged and expected to participate both at the dean and staff levels as the organization builds to full maturity. If your institution or library is interested in joining APTrust, please contact our Program Director, Chip German.

The executive lead of APTrust is Martha Sites, Dean of the University of Virginia Library.  APTrust staff include:

  • R. F. (Chip) German Jr.,  program director
  • Bradley Daigle, partnerships and content lead
  • Andrew Diamond, lead developer
  • Kelly Cobb, Rails and Hydra engineer
  • Christian Dahlhausen, systems administrator/developer

Member Costs and Expected Contributions

Membership dues are $20,000 per year. The consortium holds two meetings per year, the fall meeting with all institutional members, and the spring meeting for working groups. Members contribute their time throughout the year by participating in working and interest groups, and two representatives selected by the Library Dean of each sustaining-member institution serve on the APTrust Advisory Committee.


APTrust accepts all types of content from its member institutions including but not limited to: print, audio, video, and encrypted files. The annual membership fee includes 10 terabytes of content, and members may purchase additional capacity in increments of five terabytes. Institutions may designate whether their content is to be shared among consortium members.

Governing Board

The Governing Board is the primary governing body for APTrust; however, member institutions contribute actively to governance through input gathered by the Board. The Board defines and recommends strategic direction to help meet operational and strategic goals and provides advice and oversight for the budget and finances. The Board meets quarterly in person or by phone and holds an annual meeting of the Board with all institutional members.

APTrust is legally constituted as part of the University of Virginia. Activities and operating guidelines of APTrust are subject to the rules and policies of the University of Virginia, as are the contracts between individual member institutions and the University of Virginia. In the case of conflicts between APTrust operating guidelines and member institution contracts, contracts take precedence.

Winston Tabb became Sheridan Dean of University Libraries and director of the Sheridan Libraries in September 2002. He had been associate librarian at the Library of Congress. Since his arrival at Johns Hopkins, Tabb has accepted additional assignments as dean of the university's museums.

As dean of the libraries, Tabb directs the integration of new information technologies throughout the university's libraries and, as head of the University Libraries Council, leads and coordinates Johns Hopkins' entire system of libraries, which includes the Welch Medical Library and its satellite libraries; the Mason Library at the Nitze School of Advanced International Studies in Washington, D.C.; the Friedheim Library at the Peabody Conservatory; and libraries at the Johns Hopkins regional campuses and centers for part-time study in Washington, D.C.; Rockville, Md.; Columbia, Md.; and downtown Baltimore.

He is also director of the Sheridan Libraries, which include the Milton S. Eisenhower Library at the Homewood campus; the George Peabody Library at Mount Vernon Place in Baltimore; the John Work Garrett Library at Evergreen Museum & Library; and the Hutzler Undergraduate Reading Room at Homewood. Tabb also is dean of the university's museums, overseeing Homewood Museum and Evergreen Museum & Library. Both are open to the public for tours, arts exhibitions, concerts and other events, and both are also increasingly involved in the academic life of the university.

In July 2006, Tabb was appointed for a two-year term to the additional university-wide role of vice provost for the arts. In that position, he oversaw the implementation of the recommendations of the Homewood Arts Task Force, which he chaired, and coordinated efforts to extend its work across the university. Tabb also was charged with developing a strategy for funding arts initiatives and with building relationships with arts organizations in the greater Baltimore community.

Before coming to Johns Hopkins, Tabb had been at the Library of Congress since 1972, in a variety of roles. As associate librarian since 1992, he had managed 53 of the library's divisions and offices with more than 2,400 employees. Within his areas of responsibility were cataloging, circulation, the reading rooms, special collections, archives, preservation and the presentation of digital materials online.

A native of Tulsa, Okla., Tabb graduated from the Oklahoma Baptist University and went to Harvard University as a Woodrow Wilson fellow, earning a master's degree before serving in the U.S. Army as an instructor of English in Thailand. He earned his degree in library science from Simmons College in 1972 and was one of six outstanding graduates recruited that year to join the professional staff of the Library of Congress.

Sarah C. Michalak is Associate Provost for University Libraries and University Librarian. Sarah came to the University of North Carolina from the University of Utah, where she served as director of the J. Willard Marriott Library for nine years. She has also worked at the University of California, Riverside and the University of Washington.

Michalak served two terms on the Association of Research Libraries (ARL) Board of Directors and as chair of the ARL Public Policies Steering Committee. She is the chair of the HathiTrust Board of Directors and she is the past chair of the Board of Directors of the Center for Research Libraries. Two of her favorite projects were serving as the librarian lead on construction of the Allen Library at UW and hosting the North Carolina Literary Festival.

Linda Newman is Head of Digital Collections and Repositories at the University of Cincinnati Libraries and has had a 30+ year career in Libraries focusing on systems support, digitization and software development. She is currently leading a team of software developers who are building a digital repository using the framework provided by Project Hydra.

Newman asserts that APTrust will provide an essential layer of long-term preservation for the repository ecosystem presented by the Libraries to researchers, faculty and the university. She knows that faculty trust libraries to preserve physical materials and looks forward to APTrust allowing preservation to be confidently extended to the digital realm.

Greg Raschke is the Associate Director for Collections and Scholarly Communication at the NCSU Libraries where he leads programs to build, manage, and preserve the Libraries’ extensive collections. His responsibilities include overseeing the collections program and the development of digital collections.

The Formation of the Academic Preservation Trust

In August 2011, University of Virginia Dean of Libraries, Karin Wittenborg, and James Hilton, then Chief Information Officer, convened a meeting of colleagues from six universities (Duke University, Emory University, Johns Hopkins University, University of Maryland, University of North Carolina at Chapel Hill, and North Carolina State University) to discuss the challenges of preserving the growing amount of digital content. The group discussed the possibility of aligning each institution’s preservation efforts to:

  • preserve the scholarly record in ways that would allow the digital copy to be the copy of record
  • provide sustained funding for digital preservation of the scholarly record
  • accomplish more together

Coalescing around the need to preserve academic content and believing a community approach would be more productive, they created a consortium, Academic Preservation Trust (APTrust), that was committed to creating and managing an aggregated preservation repository.

The group invited five additional like-minded institutions to become founding members of the consortium: Columbia University, University of Michigan, University of Notre Dame, Stanford University, and Syracuse University.  

Each of the founding members recognized the value of leveraging joint resources and defining common goals. With these principles, the Academic Preservation Trust was born. 

The solid alignment of the members was instrumental in creating this value statement:

The Academic Preservation Trust (APTrust) consortium is committed to the creation and management of a preservation repository that will aggregate academic and research content from many institutions. Solutions will be based on respected open-source technologies that are scalable, sustainable, and provide audit functionality.

As part of a national strategy for long-term preservation, the APTrust repository will serve as a replicating node for the Digital Preservation Network (DPN). At the local level, APTrust will provide a preservation environment for participating members, including disaster recovery services. By leveraging the expertise and resources of multiple institutions, APTrust will realize economies of scale and increase value for all members.

The consortium will work together to determine the shape of future services and best practices as they align around solutions for the common good.  Ultimately, APTrust will enable academic libraries to protect the scholarship produced by the academy, a value that will transcend us all.*

Currently the Academic Preservation Trust includes 17 members from public and private institutions. It remains a consortia that values collaboration among the deans of libraries, technologists, and content specialists from each member institution.
