Well, actually, there's so many on this zine site: Side By Side, that I thought I'd just link the main site and let whoever's interested peruse the fics there as they wish. Many wonderful stories there ranging from drabbles to mini-novellas, drama to parodies.
Generally, though, I think the later editions have better qualities of writing than the earlier ones. So might be good to read the zines backwards by issue. Of course there are a few fics that are spread over two issues, but I don't think there are more than two or three of those.
Edit: And I suppose I'll also plug my favorite one from that archive - Through the Looking Glass, by Rari, from Issue #7. Features a guest star of the Mirror!Spock, who's a cool character in his own right, both on the show and in that fic.
