Some academic libraries have significantly developed and are applying some knowledge management (KM) principles and practices in the provision of library services. KM has been implemented in commercial and business environments towards achieving operational advantages. Its principles and tools can help libraries to improve performance and fulfill their mandate. By using a case study approach, the objective of this research was to find out how knowledge is identified, captured, shared and retained in order to enhance performance and improve the quality of service in the Metropolitan College of New York (MCNY) library.
