There is no such thing as a "2013 FAR/AIM" (or any year for that matter) from the Government. The AIM is published every other year (last was February 2012 with three change notices every six months in between, last was July 2012).
The FARs are updated each January as far as the "annual edition" goes, but in fact, the OFFICIAL version is whatever they were last revised to which can happen at any time in the year. The NTSB 830 is part of Title 49 and is updated in October.
What ASA or Jepp or TAB puts in the volume they call "FAR/AIM 2013" is a figment of their interpretation as to what is current at the time they publish it.
