Knowledge has been used by several organizations to plan smart and effective actions. Knowledge Management (KM) research has been undertaken in a variety of fields or disciplines. The goal of this review was to examine knowledge management strategies in libraries and information centres and barriers that prevent these strategies from being implemented. A systematic review of 42 articles from 2001- 2021 was conducted. The review covered studies on both quantitative and qualitative research approaches. Findings of the study revealed that much has not been written on the concept of knowledge management strategies. Lack of knowledge on the concept coupled with lack of knowledge sharing and lack of technological infrastructure were identified as some of the barriers to knowledge management practices in libraries and information centres.
