Social Justice in Library and Information Science addresses an urgent need for more credible, accurate, authoritative, authentic, and current experiences about library and information science (LIS) research, practices, policies, and services in the Islamic Republic of Iran. The collection of edited contributions focuses on how social justice and social equity is emerging as a powerful force in shaping contemporary LIS developments in Iran. The experiences capture the complex nuances of intersecting realities in local context, unrepresented voices, and empowering efforts in LIS to overcome marginalizing conditions and circumstances. Chapters include the participatory (and engaging) aspects of LIS (including academic libraries, public libraries, special libraries, LIS education, and more) that document empirical evidence and current scholarship on how progressive institutions and fearless change agents in LIS are promoting social justice outcomes and impacts via information-related work.
