The inadequacy of information resources is a common challenge facing libraries in developing countries. The open access initiative presents the library with the solution to this challenge by providing access to high-quality journals, books and other information bearing resources. This paper considered what constitutes open access resources, reasons why libraries should embrace them, the sources and web addresses where libraries can find them and the barriers to their integration into Nigerian libraries. The paper recommends that libraries and library associations should embark on awareness campaigns to popularize OA resources, while accreditation authorities make it a minimum requirement for accreditation of programmes. Full support and adequate funding for OA projects were also recommended.
