Law and Its Discovery: The Roles of Law Librarianship and Legal Information Science in the Age of GenAI

This article examines the relationship between law librarianship and legal information science in the age of generative AI (GenAI), arguing that closer integration between the two is essential to navigating a rapidly evolving legal information landscape. It contends that law librarianship—long grounded in stable classification systems and cognitive authority—must adopt the analytical methods of legal information science to remain effective in the digital era. Together, these fields can reinforce the rule of law by improving the organization, retrieval, and stability of legal information. The article identifies emerging subfields of legal information science that support this integration and develops several concepts in detail, including rule of law and Thin Theory, Ecologic Holistic Media Theory, heuristics for evaluating GenAI, the relationship between rule of recognition and cognitive authority, and the use of GenAI-informed taxonomies for classifying legal cases. By aligning the core values of law librarianship—intellectual freedom, equitable access, and preservation—with these analytical tools, the article offers a framework for sustaining legal research, education, and access to justice in the GenAI era.
