If you do not see a fantastic purple background, please click here for a less beautiful backgrounded page of Buffy links.
Favorite ones are marked with this:
Addictive Stigmata Sandycat’s fanfiction archive (named years before the movie Stigmata came out) with Aus/S/D, B/S, W/S,
Bookshelf/ The Mauz The fics here are primarily B/A, whole cast, and/or what-if’s and what-really-happened-during-the-episode.
Bucky’s Fondue Hut : a C/X site that house my very own first fic! This is run by one of my very favorite Cordelia authors.
Buffy Cross & Stake this site is ideal if you’re looking for episode summaries, spoilers, cast bios, etc. It’s very professional looking. The fiction is mostly G through PG-13 with only a little R and no NC-17. Couples included are B/A, S/D, B/S, B/X, B/R, W/S, W/O, W/X, W/A, and C/X.
"By Sun and Candlelight" no longer seems to be found at http://www.stas.net/bysun/home.html ...: a site of Angel/Cordelia fanfic, ratings range from PG to NC-17. Though the site only has a few stories, it has some great links to other Angel(us) sites and Cordelia sites.
Decaf Land a site devoted to Cordelia/Giles that was originally created by Melissa Flores, one of my very favorite Cordelia writers and now run by another great author. Also, the page has a very detailed page of Buffy links (including C/X, O/W, B/A, W/X, B/X, B/S, W/S, W/G, C/O, W/A, G/J, B/G, C/S, C/G, A/C and a few more random ones) that you should check out.
Evil Twins (which has moved to a new site!) Index to Lex and Tam's other pages. They also have an Aus/B adult fic archive and individual pages, but it would take too long for me to list them all. If you love adult B/A stories, go here.
Eyeballs to Entrails Willow/Spike fanfic and lots of it! Some of my favorite W/S writers are archived here. Ratings range from PG to NC-17.
Fever of Fate archive all Willow fic, so has W/S, W/A, W/X, W/O, and some Willow slash
Genie Janelle's fanfic which no longer seems to be at http://www.angelfire.com/nc/GenieJanelle/entry.html ... This is a really fun site with episode summaries, episode quizzes, character quizzes and so much more. Her fiction is mostly B/A and fics written by request. Her front 2 pages have music, so if it’s late at night, skip directly to the fic page.
Lady Farcly's Erotic BtVS FanFiction The Fiction includes A(us)/S/B, A(us)/B, B/S, and A(us)/X.
Moon Madness: Home to Laure Alexander fiction. Laure is the author of TEAOWS (The Erotic Adventures of Willow & Spike) universe which includes some really good Willow/Spike & Buffy/Angelus fiction, but she also has B/S, Aus/X, S/B/A, C/A, Aus/S/D, and much much more. There’s lots of NC-17, slash, and varying degrees of BDSM.
Love’s Bitch : a site primarily devoted to B/S but with many more pairings
Naughty Slayer Archive Lex and Tam's archive of B/A fiction. Other people can be included, but B/A must be the main point and they all have “adult themes”.
Nickle’s Fan Fic : a site devoted to Cordelia, whether it be C/X, C/G, or C/O.
Nicollette Marquis McFadgen (Niccy) fiction : Niccy is another great author. She’s specializes in series that focus on G/X, B/X, C/O, C/X, Aus/X, O/X/Devon, X/Larry, O/X, Aus/S, W/X, A/C, C/D, and more combinations with ratings from PG to NC-17
Ring of Unconventional BtVS Relationships: webring devoted to those relationships not explored on the show
Saber ShadowKitten’s stories She is another one of my favorite writers, especially her A(us)/S and B/S stories. She’s also got W/A, S/D, C/A, C/X and S/X with ratings from G to NC-17.
Unconventional Relationshippers There are over 2300 stories devoted to those ‘ships not explored on the show, both slash and het. If you’re looking for a certain couple, it’ll be here.
Obsessed Maniacs While there’s no fanfic here, there are episode summaries, pictures, and bits of news for both Buffy and Angel.
Salty Goodness Cult of Angel/us Addicts The page was still quite empty as of 8/30/00, but it looked like there was quite some potential. There’s a fic page, a picture gallery, and a quiz.
Sunnydale High School there’s no fiction, but there are so many pictures! This is another great place for summaries and background info.

The X-Files Romantics Fanfic Archive: mostly, if not all, Mulder/Scully romance fics
