This document discusses the use of robots in libraries. It describes how over 25 libraries, especially university libraries, have implemented Automated Storage and Retrieval Systems to replace stacks and store their entire collections in a centralized location. It provides examples of robots used in specific libraries, such as Charlie the robotic book trolley at the National Library of Australia, and Vincent and Nancy which are NAO robots that join a makerspace program at Westport Public Library. The document also mentions how makerspaces and 3D printing technologies are becoming more common in public libraries.
