March 2026 Release Notes

The March 2026 GovInfo release comprised 85 individually tracked changes. Highlighted features included a focus on supporting new content, such as United States Reports volumes up to volume 582 (2017), progress on digitized historical Congressional Serial Set volumes, and additional digitized U.S. Statutes at Large volumes in USLM XML. This deployment also included a new related documents use case that displays related Congressional hearings on Congressional bills collection Content Details pages. A “Clear” function on the search box widget was also implemented. The migration of Content Details pages to the new framework continued with the completion of the Congressional Bills, Congressionally Mandated Reports, Senate Manual, House Journal, House Rules and Manual, and Public Papers of the Presidents collections. There were also security patches and component upgrades, design improvements, collection and system enhancements, bug fixes, and more.

New Content and Features

It was a vibrant period of content submission to GovInfo. Over 64,700 content packages (roughly equivalent to one bound printed document) were made available from January 1 to March 31.

Expanded United States Reports Coverage

One of the most exciting additions was expanded coverage of Supreme Court opinions in the United States Reports collection in GovInfo, now spanning from 1790 to the most recent volume, 582 (2017). This builds on the extensive work done in a previous release to digitize and make available the earlier volumes. It means that GovInfo now has a full run of all published volumes of the United States Reports, a significant addition to the GovInfo Judicial branch corpus. There are now 30,788 individual Supreme Court cases published in GovInfo.

Full Run of Statutes at Large in USLM XML Format

Improving transparency through format conversion activities is a priority for GovInfo to support its broad user community. Nowhere is this more evident than in efforts to produce USLM XML files for volumes of the United States Statutes at Large. In this release, Volumes 1-28, 36, and 64-79 were made available in USLM XML format in GovInfo. With this achievement, all Statutes at Large, the permanent collection of all laws and regulations enacted during each session of Congress from 1789 to the present, can now be accessed in USLM XML format, as well as in the original PDF. View the USLM XML on the browse page, through bulk download, and from package-level search results.

Congressional Serial Set Growth

The U.S. Congressional Serial Set continues to proliferate in GovInfo. There were 15,263 digitized Serial Set reports, documents, and journals published in GovInfo from January through March 2026. In January, GovInfo achieved a major milestone of 10,000 total volumes in the system. This ambitious undertaking has been a successful, multi-year effort, with only about 4,000 volumes remaining until the project is complete.

Feedback about improvements is key to ensuring user satisfaction. By request, the team added an “X” clearing function in the search box to quickly clear entered search terms. The “X” appears after executing a search so that you can easily start over.

Related Documents Linking Congressional Hearings to Associated Congressional Bills

The team built an important new legislative use case for GovInfo’s Related Documents functionality. This linking now connects a related Congressional hearing to a Congressional bill on the bill’s Content Details page. Specific to this use case, the relationship is defined by connecting to the bill number(s) that are referenced on a given hearing's cover page. References within the hearing's full text to a bill will not be displayed on bills pages.

Hearings are meetings or sessions of a Senate, House, joint, or special committee of Congress, usually open to the public, to obtain information and opinions on proposed legislation, to conduct an investigation, to evaluate, or to oversee the activities of a government department or the implementation of a Federal law. The linked Congressional hearing document will now appear on applicable Content Details pages under the “Related Documents” tab. This information is also available via the GovInfo API.

Below is an example for HR.1 – One Big Beautiful Bill Act, which links to the hearing for this legislation that was held on May 21, 2025.
