The session will discuss a study conducted by a librarian research team at an R1 university that began testing the new Ex Libris Primo AI Research Assistant in 2024. The research team created a framework to assess the quality of results produced by this tool by inputting one year of research assistance queries from undergraduate writing program students and further comparing the output of a basic search to a prompt-engineered approach. Study findings will be presented along with a discussion of how librarians adapted their practice to integrate this AI tool into instruction and consultations.
