Social media have taken a lead in academic libraries; however, there are still questions on how libraries are using social media tools to enhance their service delivery. The aim of this exploratory study was to investigate the use of social media tools by library staff working in the University of South Africa’s (Unisa) main library on the Muckleneuk Campus. Since it was realised that not all staff members use social media tools in the execution of their daily tasks, the first objective was to establish which staff members do use social media tools and for which purpose the tools are being used. A further objective was to learn about the potential advantages of social media tools to improve service delivery. The study also endeavoured to acquire an understanding of the challenges that social media tools present to its users. Based on the literature review, it could be established that libraries, and specifically academic libraries, utilise social media for marketing, dissemination of information, reference services, and communication with users and to answer student queries. The reported findings of this study concur with the findings reported in the literature review. The empirical data, which were collected through a qualitative survey questionnaire and interviews with library staff who use social media tools, revealed that only staff who communicate with library patrons, namely information processors and marketing staff, use social media tools. The findings also showed that the Unisa Library has specific guidelines and policies that guide the use of social media tools to interact with users, market the library and communicate events and service delivery changes.
