The emergence of technologies has greatly exposed libraries to connecting their facilities and resources for seamless sharing and transmissions. Consequently, networking is one of the technological tools aiding the operations and services of libraries. This paper addresses the need for deploying Li-fi for revolutionising networking in the library. This paper adopts typology design to provide a more precise and nuanced understanding of Li-fi, pinpointing and justifying key dimensions of it and its deployment in libraries. Findings revealed that Li-fi is potentially suitable for varied library services including makerspaces, the metaverse, online gaming, digital reading, OPAC, virtual reality (VR), augmented reality (AR), video streaming, remote control systems, and smart libraries. Findings further showed that the major pros of Li-fi are that it increases the network security, speed, availability and minimises external interference in the data flow, while its cons include confined range and compatibility. This paper concludes that the development of Li-fi presents libraries with enormous opportunity to provide state-of-the-art services enhanced by cutting-edge technologies while minimising security risks and misuse of library data.
