University libraries in Nigeria exist to support teaching, learning and research needs of their parent institutions. This is done through the provision of up-to-date information resources to their clientele students, teaching and non-teaching staff. This mission can be best accomplished through effective marketing of information and library services to their respective users. This paper examines marketing of information and library services in Nigerian university libraries; the current situation and the way forward. Marketing of information and library services is a social and managerial process by which individuals and groups obtain what they need and want through creating and exchanging products and value with others. The use of Marketing mix (the 7p's) and other marketing strategies such as exhibition, segmentation and use of Internet were seen as means which could be used to market information and library services to various users in Nigerian University Libraries.
