Many, if not most of the JAG related sites which are found on the internet, have been abandoned after only a few years of the series and are therefore mostly historical. A few are maintained up-to-date with episode listings but contain only short cryptic "TV guide" type synopses. The sites I find most worthwhile are given below. [Links were checked valid on: 1 Oct 2011]
REAL Official JAG Sites:
The official site of the US navy Judge Advocate General
Staff Judge Advocate to the commandant of the Marine Corps
US Air Force JAG
The official site of the Canadian JAG
US Military Enlisted Insignia
Military medal pages from the Australian Department of Defense web pages.
Great military photos
Official JAG Sites:
JAG series syndication on USA channel. They are now pretty much the “keeper” of the franchise.
The JAG series aired on CBS before they abandoned it in its prime. This web page pretty much has NOTHING on it but is left up for “completeness sake.”
JAG fan sites
A David James Eliott fan site which is still very active. Currently updating their screenshots of each episode.
Site limited to Catherine Bell – Mac. Quite well done.
JAG TV Sites:
1995 only – free portion of pay site
Fairly up to date
