US federal government information sources

By law, the US Government Publishing Office is the "official, digital, and secure source for producing, protecting, preserving, and distributing the official publications and information products of the federal government," making it the world's largest publisher.  Government "documents"  range from tourist brochures to long books, speeches to astronomical data, gardening advice to technical reports, budget reports to the laws of the land. 

Most GPO publications have been published online since the late 1990s and are listed in our library's Discovery Search (Primo) catalog: GPO has had an online-only publication policy since the early 2020s.  

Extensive digitization of older documents (including many outside GPO's mandate) has been done by government agencies, by commercial database vendors (Voxgov, HeinOnline, ProQuest, Readex), and by nonprofits (LLMC-Digital, HathiTrust, Internet Archive); see entries for their collections elsewhere in this guide or in the libraries Databases A-Z directory.

The library's physical "Docs" collection is in a special section on the 5th floor of Newman library, identified and stored according to GPO's unique "SuDoc" call number system; you can find them in our <em>Discovery Search</em>  catalog.  Many printed government publications, dating to the early 20th century, are in offsite storage. (Plus some federal publication series are cataloged using the more familiar Library of Congress call numbers and shelved in the main collection.)  Don't be reluctant to ask a librarian for help.

Understanding the SuDoc number is crucial for getting your hands on physical government publications in the library.  William & Mary has a good guide to How to read a SuDoc number

Accurate SuDuc numbers are necessary for requesting delivery from library storage or from other libraries via ILLiad.  You can find SuDoc numbers in:

For earlier SuDoc numbers, it is often faster and easier to use the print indexes to the Monthly Catalog of U.S. Government Publications, 1895-2004, shelved near the Docs stacks (start at call no Z1223 .A183) than to fight with the online PDF indexes of  US government documents from GPO.

US state governance information sources

Acquiring records under state open records/open meetings laws

State laws vary from one another and from the federal Freedom of Information Act.  The following guides have different strengths; compare their coverage before requesting a state or local record.

  • Reporters Committee for Freedom of the Press Open Government Guide provides detailed descriptions of the coverage of each state's law.
  • National Freedom of Information Coalition (University of Missouri) State Freedom of Information Laws includes sample request letters and summarizes resources for all US states.

Think tanks, policy papers, "gray literature"

Professors and other people with advanced academic degrees present their expertise in other settings beside peer-reviewed journals and scholarly books.  They may produce reports and analyses for governments, non-profit organizations, corporations, and all sorts of research institutes; they also distribute research for comment at academic conferences.  While these sources are often created with academic rigor, they commonly do not go through full peer review before publication.  Nonetheless, especially regarding recent events and hot topics in politics and policy, such "gray literature" can be important bridges between journalism and traditional academic publications. 

Preprints, conference proceedings

Intergovernmental and nongovernmental organizations

Intergovernmental organizations (IGOs) and private, nongovernmental organizations (NGOs) often partner to address social, environmental, economic, technical, and human rights issues.  For research on topics on transnational and international concern, it is often appropriate to search both kinds of entities, using the same search terms.

IGO Custom Search Engine

The IGO Custom Search Engine searches across hundreds of IGO websites, including the United Nations, World Bank, UN Development Program (UNDP), Organization for Economic Cooperation and Development (OECD), European Union, the Asian Development Bank, and many others.

NGO Custom Search Engine

Like its IGO counterpart, use the NGO Custom Search Engine search across hundreds of NGO websites worldwide.


These Google Custom Search Engines (CSE) are a project of the International Documents Taskforce (IDTF) of the American Library Association (ALA). For more background on this project, including links to the IGo and NGO lists included in these searches, please see the IDTF wiki.
