As art libraries face challenges from an evolving environment, repercussions from the COVID-19 pandemic, and static or diminishing resources, finding sustainable pathways forward becomes an increasing priority. An important option for art research collections in achieving long-term sustainability is collaboration. This report explores opportunities for collaboration between art, academic, and independent research libraries and models how quantitative analysis of library collection and activity data could be used as evidence to support decision-making about collaborative opportunities. It is intended to help support art libraries and their leaders in the ongoing stewardship and availability of art research resources. The report uses two approaches: (1) Collective collection analysis and (2) Resource sharing activity analysis. These analyses provide insight into the current state of the network of libraries supporting art research in the US and Canada, highlight the unique value art libraries can bring to partnerships, and point to possible future collaborative efforts around building, stewarding, and sharing art research collections.
