This document summarizes a workshop that used Lego Serious Play methods to envision the future of academic libraries. Participants worked in groups to build models of future library spaces and services using Lego bricks within certain time and resource constraints. They considered elements like study spaces, collections, teaching/learning support, IT services, and more. Groups then presented their models and shared ideas on key services libraries cannot live without. The workshop aimed to encourage innovative thinking around building future academic libraries to thrive.
