This study sought to investigate how the self-archiving of scholarly publications in Open Access Institutional Repositories can be strengthened for improved access to local content. Specifically, the study sought to investigate factors that influence self-archiving of scholarly publications in OAIRs, examine the implementation of OAIRs policies on self-archiving of scholarly publications in OAIRs and determine challenges that hinder self-archiving of scholarly publications in OAIRs. The population of the study consisted of 2894 faculty members and 413 sample size, obtained through a systematic random sampling technique. Data were collected using questionnaires and interviews with eight key informants. Key findings indicated that there are factors that influenced self-archiving of scholarly publications in OAIRs among faculty members such motivating factors, availability of technical support, supervisors/peers/colleagues and supporting services. Moreover, the study found challenges that hindered self-archiving as low level of awareness and inadequate advocacy for a self-archiving, lack of personal benefit such as rewards and promotions, fear of the plagiarism, lack of enough facilities like ICT and internet connectivity. The study also found that there was a need to implement OAIR policies in self-archiving of scholarly publications in the OAIRs. In order to strengthen self-archiving, the study recommends providing support services, technical supports, encouraging supervisors/peers/colleagues, creating awareness, providing personal benefits, provide education and give more time, effort and implement OAIR policies to enhance the process of self-archiving scholarly publications in OAIRs. The findings of this study shall contribute new knowledge to the existing research outputs that have been conducted in this field.
