Sourcebook of United States Executive Agencies (First Edition)

The ACUS Sourcebook examines the agencies and other organizational entities of the federal executive establishment, including independent agencies. The results of this study are an especially valuable resource to Congress, the judiciary, individual agencies, the general public, and academic researchers in government and public administration. No other up-to-date resource of its kind exists.

The first edition of the ACUS Sourcebook, originally published in December 2012, was corrected in March 2013 prior to a second printing.  For a full list of corrections, please see page vi.

A second edition of the ACUS Sourcebook was published in December 2018. The second edition has a broader reach, covering more agencies, and reflects current laws and recent scholarly research on the structure and operation of the executive establishment.
