The only way Nigerian academic libraries can remain relevant in this information age and satisfy
the teeming users who patronizes the library on a daily basis is for them to keep abreast with recent
technologies. One of such technologies is library 2.0. This paper defines and conceptualized library
2.0. It explores the present state of academic library services in Nigeria. The different types of library
2.0 technologies and its ways of sustaining library services were identified. The paper concludes that
if library 2.0 technologies are applied in Nigerian academic libraries, it will promote collaborative
learning, improve study and enrich research output, thus enhancing the educational and economic
development of the country. It therefore recommends among others that library management and
government should provide adequate funds for the provision of the technologies. Library staff should
be trained on effective handling of the technologies.
