^Well, they are
fanfic. That was the whole idea behind The New Voyages
-- to collect the best of the ST fan fiction that was out there at the time and give it broader exposure in a professional publication. Remember, at the time, the only professional Trek fiction was the Bantam novel series, most of whose entries were written by established authors who were doing it for the paycheck and weren't necessarily all that Trek-savvy. So at the time, fan fiction was generally more authentic and truer to the Trek spirit than most of the pro fiction that was available (what little there was of it). It took time for Trek Lit to mature, and TNV was a step along the way.
