Abstract
Evidence from well-established theories of various disciplines manifests that, in the current technology-led world, continued professional development (CPD) of information professionals plays a paramount role in the uplift of institutions. CPD of university library professionals via e-learning programs leads to the implementation of user-centric-services through the initiation of emerging technological tools and the latest methods of service-delivery. The focus of this study is to shed light on the factors influencing e-learning for CPD of working librarians, challenges being encountered for e-learning adoption, and to propose the best practices for designing an efficient e-learning portfolio. For meeting the focused study-objectives, the authors applied PRISMA guidelines and procedures. An extensive search was conducted utilizing the world's 16 leading e-databases and digital tools containing the most relevant core studies. Consequently, 30 impact factor research papers published in renowned databases were included through the identification, screening, eligibility, and inclusion process. Findings revealed that different factors-including organizational survival, continuous changes, adoption of emerging technologies, and professional growth-encouraged e-learning for CPD of information professionals. The study results showed that four main challenges-technical difficulties, lack of funds, reliance upon conventional models, and overwhelming work-load-were encountered for e-learning adoption. The authors proposed a framework for the development of an effective and efficient e-learning portfolio for building professional expertise among university librarians to support the organizational vision and mission statement. The recommended framework is based upon emergent categories and sub-categories extracted via thematic analysis of the existing empirical studies. This study has theoretical insights for the researchers through valuable addition in the body of literature and practical considerations for policy implementers to construct sustainable policies for devising e-learning programs to develop professional expertise in the university library workforce for attainment of value-added outcomes.
