The aim of this paper is to determine access provision for sight-impaired students (SISs) in Nigerian university libraries. This is based on the principle that accessibility to available information in the library is a necessary fulcrum for effective use of information resources and services and the satisfaction of the information needs and educational growth of people in a community. Sight-impaired students refers to students who have sight disability. The main objective of setting up university libraries is to support and encourage scholarship and research in all fields of human endeavor, irrespective of abililty/disability. Thus, this paper examines the concept and characteristics of sight-impaired students and the role of Nigerian university libraries in serving SISs. The paper examines the gaps between available information resources and needed information resources, the challenges Nigerian university libraries face in filling the gaps, and makes relevant recommendations for enhancement of access provision for SISs.
