As academic research libraries in the United States shift towards a fully digital, on-demand, and data-driven collection infrastructure, librarians at these institutions have steadily adopted the CELUS platform to address their increased reliance on usage statistics, which are vital for maximizing budgetary investments in scholarly e-content.
Among the nearly 200 institutions with an R1 Carnegie designation, over 25% are CELUS subscribers or currently engaged in robust evaluation of the platform. Since January 2026, more than a dozen R1 institutions have adopted CELUS:
When asked to comment about the leading factors driving research libraries to adopt CELUS, librarians Michelle Turvey-Welch and Betsy Tucker at Kansas State University, a long-standing CELUS customer, explained:
“Celus is an excellent specialty tool for COUNTER API (SUSHI) harvesting. It allows us to get a holistic look at the state of our credentials at any given time, which allows us to fix things proactively at the time that they break rather than reactively at the time of renewal. Its’ tools for generating reports based on that data are intuitive and easy to use. The cross-platform comparisons are also incredibly useful when we’re trying to figure out where things are getting used. The ability to manually ingest and visualize non-COUNTER statistics is something I haven’t seen in other similar tools.”
Ken DiFiore, Library Ambassador at CELUS said, “At CELUS, we have a deep appreciation for the cultural heritage role that US-based academic research libraries play in bringing knowledge and professional expertise in an equitable and affordable manner to society. We’re delighted that our innovative platform for managing and analyzing e-resource usage stats is helping research libraries deliver on their mission.”
About CELUS
CELUS provides librarians with an online, cloud-based platform for the dynamic harvesting, reporting, and management of electronic resource usage statistics. It is the result of a collaborative effort with CzechELib, the Czech national consortium of academic libraries, which boasts approximately 130 member institutions and an annual e-resources budget of $50 million. This partnership has enriched CELUS with a wealth of experience and expertise in the field of e-resource usage statistics (www.celus.net).
