Users can search by part number or part name in the CFR within HeinOnline in multiple ways.
How to Search by Part Number
Within the Advanced Search option found on the Code of Federal Regulations homepage, let’s search for part number 160. Select the Part Number field from the drop down menu and enter in the desired number.
This will provide results of any time part number 160 is found across the CFR over time. Use the date range facet to refine your search further.
Alternatively, use the one- box search with the Code of Federal Regulations database to search by part number. For example, enter part:(160) into the one-box search and select the Just Search for option.
This will produce the same results as the Advanced Search.
How to Search by Part Name

The results will display any instance where the part name Ports and Waterways Safety appears within the CFR across time.
To locate the title name using the one-box search, enter the title name with the specified syntax part_title: and use the Just Search for option.
