“As early as 2003, certain university libraries in the US developed virtual libraries in the online video game Second Life and offered a variety of services, marking the first practical research on metaverse libraries. The metaverse is regaining popularity nearly two decades later, and technological circumstances have improved. Today’s metaverse is a collection of new technologies, including virtual reality (VR), augmented reality (AR), gaming, networking, etc. VR and AR are two of the most important metaverse enabling technologies, and their use in university libraries is growing.”
