This paper is a position article that explores the various ways that have been missing in the decades of advocacy for the use of Open Educational Resources (OER) in universities in Nigeria. The paper examines both the global and Nigerian perspectives in the advocacy for the use of OER. It also explains exhaustively the concept of OER. The paper identifies institutional support, awareness of the existence of OER in the university communities, adequate bandwidth with sustained ICT capacities and facilities, sound policy framework and public-private partnership initiatives as measures that are missing in the chains of advocacy to popularize use of OER in teaching and learning in Nigerian universities. The paper firmly believes that when these issues identified are properly addressed and interlinked, the awareness of existence and popularity of OER in teaching and learning in universities will be boosted which will ultimately lead to their incorporation in the nation’s university curriculum content and processes.
