What is EAASI

EaaSI is open-source software, managed by Yale’s project team, that facilitates interactive, controlled access to digital cultural heritage and research by making emulation easier. The EaaSI software and user community aim to make emulation more accessible to practitioners, empowering the goals of digital stewardship organizations around the world.

EaaSI and SPN have grown up together, starting when SPN established a relationship with the Berkman Klein Center for Internet and Society regarding copyright and licensing for software preservation and reuse, which has been essential to the evolution of EAASI. Over the last 7 years, SPN and EAASI’s program team have collaborated on sustainability planning, community cultivation and various projects where SPN members have had the opportunity to utilize hosted instances of EAASI to access content ranging from design files to literary collections, research software, and beyond.

EAASI Use Cases


  • A researcher embedded scientific images into a software product their lab distributed many years ago. They now need access to the images, and don’t have the originating source. The software only runs on an older version of Windows. —Cornell

  • A curator from London is working on an exhibit of Diane Lewis’ work. They sent a researcher to review her drawings, but would also like them to review her digital files to look at unpublished mockups for her books and to review the original CAD drawings for some of her projects. —GSD

  • A freelance researcher, is interested in old video games, such as Lemmings and would like to conduct a playthrough to see what it was like, and to see how Denis Johnson played it. —UT Austin

EAASI Research Alliance

About Us

The International EAASI Research Alliance, convened by the Software Preservation Network, is an international EaaSI user community of libraries, archives, and museums that utilize the EAASI software to broaden access to digital collections of culture and scholarship.

Together these organizations explore how the EAASI software can be used to provide and preserve access to software-dependent collections for educational and research purposes. The EAASI Research Alliance Subcommittee was convened following the vote and has been actively engaged in planning for the launch of the Alliance ever since.


How We Work

The charge of the Subcommittee is to oversee progress of Yale + SPN/Educopia EAASI Research Alliance organizational collaboration and lead continuous monitoring and assessment. The group meets bi-weekly. The members of the Subcommittee represent key SPN stakeholders, including:

  • Eric Kaltman, SPN Coordinating Committee Strategic Coordinator
  • Chelle Sanders, SPN Program Manager
  • Jessica Meyerson, Educopia Co-director
  • Wendy Hagenmaier, Yale’s Head of Software Preservation and Emulation
  • Kendra Albert, SPN Law and Policy Advisor
