The Heritage Library of the National Library and Information System Authority (NALIS) evolved from the integration in 1994 of the West Indian Reference Library of the Central Library Services of Trinidad and Tobago and the West Indian Reference Section of the Trinidad Public Library.
The Heritage Library is a key contributor to the future of our culturally diverse population. It is committed to promoting a sense of self by presenting the Trinidad and Tobago society to itself through the preservation of the nation's Heritage Collections and building the Oral History records. Its main role therefore, is to acquire, preserve and promote information in all formats, on or about Trinidad and Tobago. In addition, the Heritage Library houses the Legal Deposit items and acts as a national depository and resource for materials published in Trinidad and Tobago.
