The Jamaica Library Service provides under the Ministry of Education and Youth, a Public Library Network and a School Library Network. The organization is managed at two levels through a Central Statutory body - the Jamaica Library Board and the local Parish Library Committees.

The Jamaica Library Service exists to
enable national development through the creation and support of a knowledge-based society of culturally aware lifelong learners by providing universal access to information. This will be achieved by being customer-focused and technology-enhanced; in an aesthetically pleasing environment; and by a well-trained, competent, motivated and empowered team.
