"We preserve our digital library and repository content to ensure future accessibility and usability of digital assets using local digital preservation systems and geographically distributed digital preservation networks such as MetaArchive and Academic Preservation Trust, and by performing a biannual crawl and harvest of Virginia Tech's web presence using Internet Archive's Archive-It service."
See our Preservation Policy for specific information.
The purpose of our preservation system is to preserve all digital assets produced by the Viriginia Tech Libraries, which largely includes scholarly communications and content produced in library projects.
The Imaging & Preservation Department is a part of the Research & Informatics Department and collaborates with several other departments, sub-departments, studios, and groups regularly, including:
This is a diagram of the digital preservation workflow for content at Virginia Tech University Libraries. This process is managed by the Digital Imaging and Preservation Services Department (DI&PS). Content produced by Clients and Content Managers is processed through a SIP creation tool developed by the Digital Preservation Technologist that bags the content. Content is then processed through Archivematica's microservices and transferred to one of our storage servers. This entire workflow depends on other minor technologies, accesses several additional servers, and the collaboration of several departments in the library. There are also additional workflows for specialty content, such as Digital Humanities content and Creative Technologies Theses, that is still being developed.
Virginia Tech is a member of both MetaArchive and Academic Preservation Trust (APTrust). Both organizations are aimed at long-term digital preservation storage, maintenance, and security. We also maintain local copies in our instance of AWS.
MetaArchive is an organization consisting of various libraries, universities, and other institutions geared towards long-term preservation. Their storage is based on LOCKSS (Lots of Copies Keeps Stuff Safe) caches, based at Stanford University. Archival units that VT controls on behalf of other institutions are ingested into MetaArchive.
APTrust is a consortium consisting of various higher education institutions for the purpose of preserving academic content and is based at the University of Virginia. Content created at VT is processed through Archivematica and then ingested into APTrust.
See more information on our internal Storage Service through AWS.
U-Pack is a SIP creation tool developed by the Digital Preservation Technologist at Virginia Tech. This tool produces checksums in a manifest, formats basic metadata, and bags each item prior to upload to our various storage locations.
Archive-It is a web archiving service developed by Internet Archive that web crawls Virginia Tech's presence biannually. See our Web Archiving Program and the Web Archiving LibGuide for more information.
As of June 2019:
Each semester we provide 3 digital preservation courses, and occasionally additional preservation courses. See the following information on the Fall 2019 courses. This is the correct and updated information.
