From the Document: "The Freedom of Information Act (FOIA), enacted into law more than 50 years ago, requires federal agencies to provide the public with access to government records and information based on the principles of openness and accountability in government. As required by law, 118 agencies reported their FOIA activities to the Department of Justice (DOJ) for fiscal year (FY) 2018. DOJ's Office of Information Policy (OIP), National Archives and Records Administration's Office of Government Information Services (OGIS), and the Chief FOIA Officers Council each have roles supporting agency implementation of FOIA. Specifically, OIP is responsible for 'encouraging agencies' compliance with FOIA and overseeing their implementation of the Act.' OGIS's responsibilities include reviewing agencies' policies, procedures, and compliance with the FOIA, and identifying methods to improve compliance. The Chief FOIA Officers Council, which is co-chaired by the Director of OIP and the Director of OGIS, was established to assist in FOIA compliance and efficiency."
