The Law Library is largest public law library on the west coast, and second only to the Library of Congress in size of collection. The geometric Modernist building designed in 1953 by the architect firm Austin, Field, & Frye. It was one of many buildings conceived as part of the 1947 Civic Center Master Plan, a monumental plan that transformed a large portion of Bunker Hill and created the east-west axis of government buildings that frame today’s Grand Park.

The Law Library offers free classes, workshops, and 1-1 assistance to Angelinos seeking legal information and services.

In 2003, the Law Library was dedicated as the Mildred L. Lillie Building. Lillie became the second woman to serve on the Court of Appeals in 1958, which she served on until her death in 2002. She was one of the longest-serving appellate justices.
