United States Code (from Office of the Law Revision Counsel)
The download page says:
Current Release Point
Public Law 113-296 Except 113-287
Each update of the United States Code is a release point. This page provides downloadable files for the current release point. All files are current through Public Law 113-296 except for 113-287. Titles in bold have been changed since the last release point.
A User Guide and the USLM Schema and stylesheet are provided for the United States Code in XML. A stylesheet is provided for the XHTML. PCC files are text files containing GPO photocomposition codes (i.e., locators).
Information about the currency of United States Code titles is available on the Currency page. Files for prior release points are available on the Prior Release Points page. Older materials are available on the Annual Historical Archives page.
You can download as much or as little of the United States Code in XML, XHTML, PCC or PDF format.
Oh, yeah, the 113-287 reference does seem rather cryptic. What? You don’t keep up with Public Law numbers? 😉
The short story is that Congress passed a bill to move material on national parks to volume 54 and that hasn’t happened, yet. If you need more details, see: Title 54 of the U.S. Code: Background and Guidance by the National Park Service.
You can think of this as the outcome of the sausage making process. Interesting in its own right but not terribly helpful in divining the process that produced it.
Enjoy!
PS: On Ubuntu, the site displays great on Chrome, don’t know about IE*, and poorly on FireFox.
