PurposeIn this paper, we refer to the World Economic Forum in Davos, Switzerland, in 2016, where the concept of the Fourth Industrial Revolution (4IR) was coined by Klaus Schwab, with the reference that it would be building on “the Third, the digital revolution” and would be “characterized by a fusion of technologies that is blurring the lines between the physical, digital, and biological spheres”. While acknowledging that the 4IR will impact on everything, everywhere, including research and libraries, we conceptualize 4IR, and we compare current academic library services/trends in South Africa with 4IR requirements, through the analysis of 26 public university library websites.Design/methodology/approachBesides conceptualization of 4IR, a content analysis of websites of 26 public universities’ libraries in South Africa was achieved followed up with verification of the data by respective libraries through a preliminary research report circulated to them by email. 23 areas were identified as the trends in academic libraries, which included free Wi-Fi in the libraries; 24/7 study areas and access to library resources on and off campus; research commons; makerspace; borrowing ICTs (e.g. laptops); e-resources; e-catalogues; research data services (RDS; RDM, IR); open scholarship; information literacy and reference/bibliographic tools, library as a publisher, among others. Data obtained were captured in Excel and analyzed by the research questions.FindingsThe 4IR concept does not occur often in literature, in relation to academic libraries, but it is implied. The findings show that the libraries are responding well to the revolution through their services, with remarkable innovation and creativity on display. There was a 64% presence of the analyzed trends/services in the libraries, with emerging trends/services such as library as a publisher (4%), robotics/AI (4%), makerspace (8%), RDS (27%), borrowing of ICTs/devices (19%) and user experience (19%) scoring low, while information literacy and digital scholarship (e.g. IR) (88%), e-catalogue and e-resources (92%), group study area (85%) and off campus access (77%) scoring above 75%. The scatter of the trends/services among the university libraries is noted for knowledge sharing of best practice.Research limitations/implicationsIn order to improve accordance with trends, academic libraries have to be better resourced, accessed and used, as well as improve web visibility. The study expects library services to be responsive, resourced and accessible anytime and anywhere, and it provides a conceptual framework and a benchmark for further research and exploration in the country, region and perhaps elsewhere.Practical implicationsThe study can be used for benchmarking current and future academic library services in Africa. The conceptual framework provides an agenda for theoretical discussions and deliberations.Social implicationsThe trends, framework and 4IR representations in the study can inform theory and practice in LIS, particularly in Africa.Originality/valueLinking 4IR to current and future library services provides a tool for academic libraries services benchmarking and development and provides a conceptual framework for theoretical and practical debates and implementation. The study is quite current and appropriate for the ongoing discussions of 4IR implications to academic libraries.
