How to Search the Supplement Volumes of the US Code to Determine if Changes Were Made Since the Last Bound Volume
Do you have a specific provision from within the U.S. Code, but you are not sure what updates or changes, if any, have been made to the provision? For our example, we want to determine if any amendments, changes or updates have been made to 21 USC 355a, the Pediatric Studies of Drugs since the 2006 edition of the US Code was published. To determine this, we can search across the supplement volumes of the US Code that were published after 2006.
The supplement volumes of the US Code in HeinOnline have all been assigned a volseries field. Within that field we include the volume details for the supplement, such as Supplement IV, Volume 3 (January 4, 2007-January 7, 2011). This hint will allow us to search across the volseries field for the term supplement to narrow our search to just the supplement volumes. To search the volseries field, you must use the Full Text tab at the top of the U.S. Code Welcome Page.
Insert the following search string: volseries:supplement AND title_num:21 AND text:355a
Now, narrow the search to 2007-2016 using the date facets on the left side of the screen. The last bound volume was published in 2006, so we want to focus on the supplements published after 2006.
You will then see your results, all of which are supplement volumes to the 2006 Edition. Now, click on the All Matching Text Pages link to see the pages within the supplement volumes where any updates, amendments or changes to 355a are noted.
