The National Library and Information System of Trinidad and Tobago (known as NALIS) is a corporate body established by the NALIS Act No. 18 of 1998 to administer the development and coordination of library and information services in Trinidad and Tobago. As a statutory authority under the Ministry of Communication NALIS is governed by a board which ensures proper and efficient performance of the functions of the organisation. NALIS is managed by an executive director assisted by a deputy executive director and directors of its various divisions. NALIS provides library and information services at the Heritage Library (located in the National Library Building, Port-of-Spain), 23 public libraries, 4 mobile libraries, 66 special libraries, 133 secondary and 483 primary school libraries, 25 ECCE centres. Library services are also provided through its website at www.nalis.gov.tt and its social media sites: the blog, Facebook, Twitter and YouTube.

The three (3) existing Public Libraries (the Public Library of Trinidad, the Carnegie Free Library and the Central Library of Trinidad and Tobago) and their resources of buildings and stock were transferred to the new Authority.
