In this issue of World Libraries, we examine the role of libraries in responding to global challenges through two insightful articles. The first article documents the revitalization of the Tax Appeal Board of Trinidad and Tobago's library after its closure in 2006, providing insights into the development program used to reactivate its services and evaluating its success. The second article focuses on the COVID-19 pandemic and the innovative service model that African community libraries have adopted to effectively respond to this global health emergency. The article explores provisional closure of libraries, changes in circulation policy, and provision of the most trusted information. It also recommends collaborative research and practice among African librarians to enhance the quality of life in the region during and after the COVID-19 crisis. This issue highlights the resilience and adaptability of libraries in the face of global challenges, and the potential for revitalization and innovation in library services.
