Re: DS9 - Where to start?
There is also a separate license to publish ST fiction in comic-book form, and this has been held by many publishers over the decades: Gold Key in the '60s and '70s, Marvel Comics following the release of the first movie in 1979 (plus a separate daily comic strip from the LA Times Syndicate), DC Comics in the '80s and '90s, then Malibu (exclusively DS9), then Marvel, then Wildstorm. IDW has held the license to do TOS, TNG, and eventually DS9-based comics for the past several years, and for a while TokyoPop had its own license to do TOS and TNG comics in manga format, but they're out of business now so it's just IDW anymore.
If you are interested in checking out some of the pre-IDW comic books, a few years ago a company called GIT Corp released a DVD containing almost every comic released by Gold Key, Marvel, DC, and Wildstorm
. It doesn't have a couple of X-Men crossover issues, but I think those are the only non-IDW comics not on the disc.
