LLMs Directly Replace Core Reference Function
#1Frontier LLMs have crossed a quality threshold where they perform the reference interview function — clarifying patron needs, recommending sources, synthesizing information, and explaining research methodology — at parity with or above median professional librarian quality for the vast majority of patron queries. ChatGPT, Perplexity, Claude, and Google's AI Overviews have become the de facto first-stop research tool for undergraduate students, general public users, and working professionals. Reference transaction volumes at ARL libraries have declined every year since 2012, with post-2022 declines accelerating dramatically — some institutions reporting 40–60% drops in a single year.
