Artificial intelligence (AI) technologies offer enticing possibilities for maintaining, delivering, and analyzing some of the nation’s most influential research and treasured cultural and historical artifacts. Yet the use of these technologies requires extensive evaluation and monitoring before implementation. In 2025, LC introduced its AI Sandbox for Staff to do just that. The most recent cohort of the Library’s AI Sandbox for Staff supported over a dozen small-scale experiments.”
