The Knight Institute has published 12 new lists of the titles of unclassified opinions written by the Justice Department’s Office of Legal Counsel between 1959 and 1972. The July 23 release is one of a series negotiated with the OLC in response to our ongoing Freedom of Information Act lawsuit, with the latest indexes helping to shed further light on the unique role that the OLC has played for decades in quietly shaping the policies and practices of the federal government.

The latest release follows the Institute’s publication in mid-July of 14 indexes cataloging the titles of more than 1,000 unclassified opinions authored by the OLC between 1945 and 1958. Ultimately, the series of indexes will span nearly five decades and nine presidential administrations.

Explore the Knight Institute’s reading room, which houses these indexes along with more than 350 OLC opinions from 1965, 1969, 1974, and 1981 that were obtained as part of the ongoing litigation. Plus, view an index of all opinion titles produced by the Knight Institute so far.
