For example, NASA Technical Notes are listed in the catalog and are bound in numerical order in the NAS SuDoc class stem, which holds all of the documents released to federal depository library by the National Aeronautics and Space Administration (NASA). The catalog entry for this item includes the title, location, call number, and the carrier field denotes what format that material is in. This material is a bound volume.
Some technical reports were released on microfiche or microfilm. Make sure to check the catalog entry to see if the Carrier designation is microfiche/microform or if there is a note specifying this format type. The red box in the catalog entry screenshot below highlights the carrier field:
“This library is a congressionally designated depository for U.S. Government documents. Public access to the government documents collection is guaranteed by public law. (Title 44 United States Code)”
