The Hawaiʻi State Law Library System (HSLLS), established in 1966 and formally recognized in 1969 by Supreme Court order, collects, organizes and disseminates information and materials related to legal research and judicial administration.  The Supreme Court Law Library serves as the administrative headquarters for the HSLLS.  The satellite branches in the Second, Third, and Fifth Judicial Circuits are unified into one system under the direction of the State Law Librarian.  The operation of the HSLLS is governed by Rule 12 of the Rules of the Supreme Court of Hawaiʻi.

The HSLLS mission is to provide current and comprehensive legal reference and information services to the Judiciary, legal community, state and county governments, and the general public. A key aspect of HSLLS service to the general public is facilitating access to justice. Our commitment to these goals is supported by acquiring and making available primary and secondary legal resources in a variety of formats – print, electronic, microfilm, microfiche, and CD-ROMS, etc, as well as providing free access to the internet and legal research databases.
