Overview

Preservation of software is a critical component in long-term accessibility of some digital objects, which rely on a complex ecosystem of technology to be usable. Without compliant versions of software and operating systems to emulate the environments for digital artifacts like video games or modern architectural schematics, researchers cannot authentically render them. Harvard University is committed to building capacity in preserving software and enabling emulation as a method of sustainable access.

In 2021, Harvard Library became a member of the Software Preservation Network (SPN). Visit this page to learn more about Harvard SPN membership. 

Emulation as a Service Infrastructure (EaaSI)

EaaSI is a platform that enables access to digital resources using preserved software, through emulation. Developed by Yale University, EaaSI is still in beta form and being piloted by partner organizations while the programmatic logistics, including sustaining costs, are investigated and determined.

Harvard Library EaaSI Pilot Projects

Harvard currently has three projects enrolled in the 2021 Hosted Emulation Services pilot program, in partnership with the Emulation as a Service Infrastrucure (EaaSi) Program. Participating in this pilot program is enabled through Harvard's membership in the Software Preservation Network. The library units that are enrolled in this pilot program are:

• Houghton Library - using EaaSI to offer delivery of obsolescent document formats in their special collections
• Graduate School of Design - as a delivery mechanism for complex architectural records that are software-dependent
• Center for Astrophysics - to ensure sustained usability of custom software created for astrophysics research

Through exploration of software, staff, and infrastructure requirements, this pilot is a foundation for expansion of emulation support across the library.
