The organizations listed below monitor agency compliance with FOIA and developments in FOIA law; they also advocate for improved agency compliance.
"The Office of Government Information Services (OGIS) is a [FOIA] resource for the public and the government...OGIS is a place where anyone can ask for FOIA assistance. In other words, [OGIS serves] as the FOIA Ombuds -- answering questions, tracking suggestions, and providing information."
The National Security Archive maintains a collection of FOIA resources, links to articles and blog posts about FOIA, and guides to making FOIA requests.
"MuckRock provides a repository of hundreds of thousands of pages of original government materials, information on how to file requests and tools to make the requesting process easier."
"The National Freedom of Information Coalition is a resource. Our organization and members protect our right to open government by ensuring state and local governments and public institutions have laws, policies and procedures to facilitate press and public access to information and proceedings...NFOIC provides transparency education and guidance, offers financial support for FOI litigation, a state-by-state resource guide to state FOI organizations and information, and undertakes evidence-based research projects."
"The Project on Government Oversight...is a nonpartisan independent watchdog that investigates and exposes waste, corruption, abuse of power, and when the government fails to serve the public or silences those who report wrongdoing."
The Reporters Committee for Freedom of the Press (RCFP) tracks developments in FOIA law, as well as equivalent state sunshine acts, open records laws, and right-to-know laws. RCFP also maintains a FOIA Wiki.
"The Transactional Records Access Clearinghouse (TRAC) is a data gathering, data research, and data distribution organization that was founded in 1989 at Syracuse University. The purpose of TRAC is to provide the American people...with comprehensive information about staffing, spending, and enforcement activities of the federal government....Because comprehensive and relevant records about what an agency is doing — and not doing — are essential to meaningful oversight, TRAC continuously uses [FOIA] to obtain new data about government enforcement and regulatory activities."
"The goal of FOIAproject.org is to provide the public with timely and complete information about every instance in which the federal government grants or withholds records under the Freedom of Information Act (FOIA). Updated daily, this 'FOIA accountability engine' now includes detailed information on every case that challenges government withholding in federal court."
The Federation of American Scientists (FAS) operated a Project on Government Secrecy from 1991-2021. While the Project website is no longer actively maintained, it still hosts links to FOIA-related documents, and select Project resources on government secrecy are still available.
