Today, librarians are confronted with new roles during the execution of their work. The emerging roles require practical and technical skills, professional competencies and ability to perform and to constantly be in touch with those emerging technologies to stay afloat. The purpose of this research was to investigate the changing roles of academic librarians at the University of Nairobi (UoN) and its constituent college libraries in the current information age so that challenges can be established and measures put in place to overcome them. The current study employed both qualitative and quantitative approaches. The study was descriptive in nature and a survey research method was adopted. Purposive sampling was used to select respondents from each of the 13 libraries. Data was collected using a questionnaire and an interview schedule. A population of 70 respondents was to be surveyed but only 54 of them responded to the questionnaire. Quantitative data was descriptively analysed using the Statistical Package for Social Sciences (SPSS) while qualitative data was analysed using content analysis. The study revealed that the role of librarians at the UoN has not necessarily changed in terms of duties, responsibilities, functions and processes, but what has changed is the intensity and manner of conducting the role. The main challenge remains that of re-training of staff in the use of Information Communication Technologies (ICTs). Therefore the study recommended training of staff in the use of ICTs, acquiring powerful servers to increase bandwidth connectivity and allocating more funds towards various activities. The study recommends that a similar research be replicated using different groups of librarians, for example those who started working when the services were already automated to find out whether they are also as challenged as their counterparts. A further research should also be carried out to investigate current jobs that exist elsewhere in the profession, such as knowledge management, ICT management in libraries, research data management and data curation. / Information Science / M.A. (Information Science)
