Table of Classifications for Pub. L. 112-181 to 112-183, 112-186, and 112-188 to 112-195 are now available on the website of the Office of the Law Revision Counsel (uscode.house.gov). When you visit the website you will also see a link to the beta version of the new and improved (and long overdue!) website. The beta version includes not only the same content with an updated look, but additional pages that explain both the US Code and the codification process. Worth a look.
