Purpose: The purpose of the present study is to explore the possibility of introducing a 3D environment in the library by reviewing current literature and to provide a good understanding of different purposes of using this immersive environment. Design/methodology/approach: The present paper is a narrative account of libraries’ presence in the virtual world in combination with an overview of how libraries respond to the 3D environment. Relevant data for the review paper have been collected from library websites, books, journal articles, interview, etc. Findings: The study found purposive involvement of libraries in this immersive environment which indicates that users use this exciting 3D medium to satisfy their information requirement. Research limitations/implications: The paper basically considers publications containing observations of broader research community in the relevant field and contents in websites dealing with virtual world and outlines the major features as discussed in available documents. The review study infers that the implementation of 3D project in libraries requires a mindset for the specific approach, from the end of both librarians and users, together with involvement of funds. Therefore, a library may start with a beta project and observe the effectiveness from the users’ perspective before embarking on a full-fledged project. Originality/value: With numerous examples, as evident from publications and websites, the current review study makes an attempt to improve the understanding of librarians towards informed selection of projected purposes to be integrated with the virtual world from library perspective. The study also presents different approaches of libraries motivating users in the virtual world that other libraries may follow while considering their 3D library project. © 2019, Emerald Publishing Limited.
