Cite Checking Guide for Law Reviews & Publication: Regulatory Materials

Federal Regulations

Regulations appear in two official publications: the Federal Register and the Code of Federal Regulations

The Federal Register publishes chronologically, among other things, proposed new federal regulations, proposed changes to existing regulations, and the final version of the new regulations.  It is a daily publication that has continuous pagination throughout the year.  Example: 56 Fed. Reg. 50,379

The Code of Federal Regulations publishes the text of the regulations currently in force.  The C.F.R. arranges the regulations by subject across fifty titles and is published annually.  Example:  7 C.F.R. § 3.1

Federal Register

The official, online version from 1936-forward is available at, which adds the current Federal Register each day by 6:00 a.m.  You can locate regulations and other materials printed in the Federal Register from 1994 forward on, where links to the official PDF will be available in a link.

Official, PDF versions of the C.F.R. and the Federal Register are available on  

Ask a librarian if you are having trouble navigating these databases!  

How to Update a Federal Regulation

1) Use the official CFR, either in print, or in PDF from the website. Locate your regulation. Check the cover of the CFR volume or look at the top of every other page to find the “revised as of” date. You must update your regulation from that date forward. Depending upon the CFR title you are updating, you might only need to update for a month, or possibly up to a full year.
2) Next, check the LSA: List of CFR Sections Affected. The LSA is a monthly print pamphlet that is also available in PDF on the CFR main page (look in the left margin).  In the LSA, CFR titles and sections are listed in a table, in chronological order, with corresponding Federal Register citations for any amendments.
The LSA cumulates every month. You need only examine the most recent month to find all changes to your regulation since the last version in the official CFR volume, through the month of the most recent LSA. Federal Register pages will be cited in the LSA if there have been changes. If so, go to the cited volume and page in the Federal Register and read the text of the updated regulation there.  

3) At that point, you still have a gap from the last day of the most current completed LSA month, to the present day. Go to the Federal Register for last day of the month(s) beyond the LSA range. Check for your CFR citation in the CFR Parts Affected, located in Reader’s Aids, in the back pages of the FR, to fill the coverage gap after the most recent LSA. Usually, that means just the current month must be checked.  

For example: If you are updating a regulation on November 15th, and have checked the LSA for October, you need to look at the Reader's Aids in the November 15th Federal Register.  It will list citations for any changes to regulations made from Nov. 1-15. If changes to your regulation in November are cited, go to the daily Federal Registers for those citations to find the amended text.  E.g., if 82 FR 12345 is cited in Reader's Aids, that is page 12345 of volume 82 of the Federal Register. has the Federal Register in PDF up through the current business day.  Each daily Federal Register has a Reader's Aids section in the back that updates CFR changes cumulatively for the current month. So, you could check the last day of publication in each month of the Federal Register in the gap, up to the current day, as an alternative to starting with the List of Sections Affected.  


Agency Decisions

Unlike the publication of court decisions, publication of agency decisions is diffuse.  Some agency decisions will be available in print in the library and others will be available only on the Internet.  And not all agency decisions will be easy to locate. 


PDF: Federal agencies increasingly post decisions to their websites. Check the agency website for PDF versions of decisions.  The University of Virginia Library provides links to repositories of agency decisions by agency and by subject.  Selected agency decisions are available from HeinOnline and LLMC Digital.

Print:  Official agency publications resemble standard court reporters.  See the list of United States official administrative publications in Table T.1 of the Bluebook and then look for the title in MARQCAT.


PDF:  State agencies may post decisions to their websites. Check the agency website for PDF versions of decisions.  Using your favorite search engine, check the Internet for the agency website.  Once on the agency website, look for a decisions or determinations section.  The State of Wisconsin website has an alphabetical listing of Wisconsin state agencies with links to agency websites.

Print: The library carries a few selected Wisconsin agency decisions in print.  Search MARQCAT using terms from the agency name.

Other States

The library does not purchase administrative registers or codes from other states.  Check state government websites to see if they are available in PDF.  The Law Librarians' Society of Washington D.C. maintains a list of links to state administrative codes. (coverage varies by state)

Agency Documents


PDF: Federal agencies may post documents on their websites.  The University of Virginia Library provides links to government information, including agency documents.  WashLaw provides a list of agency websites with information regarding the types of documents available on each of the websites.  The Louisiana State University Libraries has compiled a Federal Agency Directory that provides easy access to agency websites.  The Catalog of Government Publications from the Government Printing Office serves as a finding tool for current and historical government publications and provides direct links to publications available on the Internet.

Print and Microfiche:  Some federal agency documents may be available in the library.  Search MARQCAT for the document, using keywords from the agency name and the document title.
