The presenters, archivists in an academic university Library, launched a web archiving program for a public university in the United States in 2018 with a three-year Archive-it contract. In the first six years of the web archiving program, we have laid the groundwork for an ongoing web archiving program through robust documentation built in anticipation of potential loss of resources, especially personnel. In this presentation, we report on a sustainability review of the program using a practical framework and a conceptual framework. The practical framework is the University of Pittsburg's Socio-Technical Sustainability Roadmap (https://sites.haa.pitt.edu/sustainabilityroadmap/). The conceptual framework is Kristin R. Eschenfelder et al.'s 2019 "Nine Dimensional Framework for Digital Cultural Heritage Organizational Sustainability" ( https://doi.org/10.1108/OIR-11-2017-0318). We describe each framework, the resulting program evaluation, and the sustainability issues and solutions we uncovered. We also outline gaps we encountered in the two frameworks by putting them into conversation with each other.
