Sierra Leone's knowledge economy stresses the importance of information for national development, and libraries have a crucial role to play in this development. Libraries are catalysts for human progress because they help in the development and transmission of knowledge and culture; they foster civic awareness in support of economic productivity and innovation in society. Although many economic programs have been implemented by the Sierra Leone government, a vast amount of information is unused, either because national decision-makers do not realize its importance or because people who might want it do not know how to access it. The public library has to play an increasingly significant role if rapid economic recovery is to be made. This article examines Sierra Leone's economy in postwar reconstruction, the importance of information and knowledge in a knowledge economy, and the problems affecting library services and how the public library can overcome these problems and make meaningful contributions to the knowledge economy.
