Many publications are available on GovInfo that are not in one of the collections listed on the What's Available page. These publications are part of two general collections, either the Additional Government Publications (GPO) collection or the Miscellaneous Government Publications (GOVPUB) collection. They can be accessed by navigating to their landing page from the Browse A to Z list or the Browse by Category page, or the individual publications can be accessed through basic or advanced search.
For example, you can access NIST Publications by:
In addition, GovInfo contains "hybrid" collections that may comprise both standard collection publications and GPO or GOVPUB collection publications. Examples are the Senate Journal collection, which includes publications from the Congressional Serial Set (SERIALSET) and Additional Government Publications (GPO) collections, or the Congressional Reports collection, which includes publications from the Congressional Reports (CRPT), the Congressional Serial Set (SERIALSET), and the Miscellaneous Government Publications (GOVPUB) collections. This is important to know because URLs and search fields may differ slightly. Not all collections can be searched using "collection-specific" search fields because the packages may not contain the necessary metadata to support those search fields.
Search by Keyword and Date Range For example, documents from December 31, 1994 to January 1, 1997 with the word debate in the text or metadata.
Search by Congress Number For example, documents from the 94th Congress.
Search by Title For example, documents with Hinds Precedents in the title.

MODS is a metadata standard that includes information about a digital object. It stands for Metadata Object Description Schema and the standard is maintained by the Library of Congress. Every single document in GovInfo has a MODS file; they can be accessed on the Content Details pages under the Download panel on the left side of the page.
You can perform a search over any field in the MODS metadata. This applies to every collection in GovInfo, and can be especially helpful for the GPO and GOVPUB collections.
