Despite the majority voting for the shorter title, I've decided to use Star Trek: The Original Series in my list. I don't buy the argument that it's an unofficial title used only between fans. This title is on all the DVD covers and the DVDs themselves, even the Fan Collectives. It's used in Star Trek Encyclopedia, Memory Alpha, Memory Beta and Wikipedia (before my edit). I've made it a policy to use retronyms in favour of original names and list stuff the way they are named in wiki articles when in doubt.
Thanks anyway guys.
