Warning: These are my own notes, made for the purpose of reminding myself what I've read and particularly enjoyed in the way of Stargate/Buffy crossover fics, so there may well be MINOR (for the most part . . . I hope!) SPOILERS contained in just SOME of the descriptions below. So, I'd advise you to skip reading the descriptions and just click on the links to check the stories out for yourself, if you're extremely concerned about plot or relationship spoilers. Otherwise, please enjoy this very incomplete listing of some of the stories I've enjoyed reading and re-reading over the years!

Buffy the Vampire Slayer crossover fics not on TtH:
SGA -- SINEYA'S WORLD by Sarhea (Teyla's team encounters a world unlike any other in the Pegasus Galaxy, populated mostly by very strong women descended from exiles from Sunnydale in another dimension; eventual Sheppard/Willow):
https://www.fanfiction.net/s/8169799/1/Sineya-s-World (or
http://archiveofourown.org/works/428748/chapters/722921).
-- WEIRDNESS IS GENETIC by Sherza (WIP, but nearly finished; during the summer after BtVS season 1 Xander discovers that Jim Ellison from Cascade is his real father, then Xander's spirit animal leads him to a newly awakened Sentinel in Colorado Springs, Clone!Jack, for whom he's meant to be the Guide; Season 2 of BtVS starts out much more promisingly, with Sentinel Jon and Guide Xander added to the Sunnydale defense forces, along with a much better trained Buffy, Willow, and Giles, thanks to Jim and Blair):
http://www.fanfiction.net/s/8050648/1/Weirdness-Is-Genetic (or
http://www.tthfanfic.org/Story-25468/Sherza+Weirdness+Is+Genetic.htm)
-- GROWING PAINS series by Wren10514 (clone!Jack/Dawn -- 1st story is straight SG1 fic, but there are 3 sequels so far with Dawn and Oz added to the mix; EXCELLENT!):
1)
http://www.fanfiction.net/s/4978831/1/Growing_Pains (1 chapter. Jon O'Neill and Cassie deal with a Goa'uld problem at the high school)
2)
http://www.fanfiction.net/s/5079618/1/Growing_Pains_2_Dawn_cometh (4 chapters. With Oz as back-up, Dawn is sent to infiltrate Colorado Springs High, where Willow's sure there's at least one case of possession by a 'Guld' demon. Sparks fly between Dawn and Jon.)
3)
http://www.fanfiction.net/s/5176517/1/Growing_Pains_3_Happy_Birthday_Jon_ONeill (1 chapter. One year after he was created, Jon's DNA starts to break down again and his friends -- both old and new -- rally in support; also, Thor is introduced to 'metaphysical energy 101' by Dawn.)
4)
http://www.fanfiction.net/s/7091223/1/Growing_Pains_3_Werewolf_Attack (1 chapter. Jon and Dawn's first date is interrupted by blood and death, which should surprise absolutely no one.)
-- ENCOUNTERS series by Elemnestra Aethelflaeda (Jon O'Neill and Cassie Fraiser have formed their own group of alien-fighting High School friends, leading to interesting encounters and near-encounters when the Scoobies settle in Colorado Springs for a while and wonder how ordinary kids got so practiced at fighting demons when there's no Hellmouth around):
1)
http://www.fanfiction.net/s/6649532/1/Indirect-Encounters (1 chapter. Running late for a demon-slaying, Buffy, Willow and Xander observe from a distance while Jon and friends expertly dispatch a tree-demon that attacks their school field trip)
2)
http://www.fanfiction.net/s/7925607/1/Near-Miss-Encounters (1 long chapter. An alien/demon incursion at the local mall results in a deepening of the mystery of Colorado Springs for Buffy and Xander, who are too late to witness Jon and company deal with the situation, this time; Jon turns out to have far more access to the power of his Ancient genes than original Jack usually displayed)
-- IN THE GENES by AlecStar (Sam Carter has a 'dumb idea' that could save the Asgard, but she needs to find a woman named Buffy Summers in order to do it, and the Scoobies are Not Amused):

-- FOR EVERY ENDING . . . series by aesop (AtS gang post-NFA turning up with new identities and missing some memories at the SGC; at the end of the first 13K word story they go off-world together, to fight the Goa'uld and live to fight the Wolf, Ram, and Hart on earth again some day):
http://www.tthfanfic.org/Series-137 -- short-fic FAR TOO YOUNG by Ava (Buffy/mini-Jack):

http://www.tthfanfic.org/Story-7614/Ava+Beyond+Hope.htm (2 very long chapters, but feels like there should've been a 3rd, to be really finished in any satisfactory way).
-- ONLY SKY ABOVE US by Ava (Joyce/Jack; 3 vignette chapters set at the start of an AU season 6 of BtVS, where Joyce didn't die from her aneurysm, and she and Dawn had moved to Colorado Springs just weeks after Buffy's death, where Joyce soon began dating Jack; only technically finished):
http://www.tthfanfic.org/Story-12677/Ava+Only+Sky+Above+Us.htm -- Funny short-fic, THE GREAT AND POWERFUL OZ by BarefootXO:
http://www.tthfanfic.org/Story-23703/BarefootXO+The+Great+and+Powerful+Oz.htm -- THE SCARAB by bktheirregular (the Goa'uld Imhotep uses Nishta to recruit demons and vamps as slaves in Sunnydale, but picks a fight with the Scoobies):
http://www.tthfanfic.org/Story-1970/BKtheirregular+The+Scarab.htm -- NEIGHBORS FROM HELL(MOUTH) series by Booster:
http://www.tthfanfic.org/Series-81 -- ALL OVER THE PLACE by Burmafrdnow (Cassie's Calling as one of the new Slayers has SG1 up in protective arms and butting heads with Riley Finn and others 'in the know'; author needs much more proof-reading, but well worth reading anyway):
http://www.tthfanfic.org/Story-25832/burmafrdnow+All+over+the+Place.htm -- BACK TO LIFE series by Burmafrdnow (Buffy is the catalyst for bringing Janet Fraiser back to life at the SGC, and hijinks ensue):

http://www.tthfanfic.org/Story-1836/captuniv+Hero+for+a+New+World.htm -- VISIONARY series by chaoseternus (Buffy, Scoobies, and SG1 unite to foil and humiliate Anubis; if you can get past the bad punctuation and misspelling, it's pretty entertaining):
http://www.tthfanfic.org/Series-77 -- DON'T WALK AWAY by cjsplace (post-"Chosen" Buffy is recruited by Thor and becomes "Kali", cleansing the worlds of evil in an ocean of blood, ending with Buffy/Daniel and a surprising change in the odds during the Angel gang's final battle in the alleyway):

http://www.tthfanfic.org/Series-1538 -- mostly SGA fic SAVING EARTH...AGAIN by DarkPhoenix (desperately in need of proof-reading, but it has its moments; Buffy is Jack O'Neill's illegitimate daughter and becomes John Sheppard's significant other, while doing the usual world-saving thing):
http://www.tthfanfic.org/Story-15739/DarkPhoenix+Saving+Earth+again.htm -- EARLY ONE MORNING by DaveTurner (Willow/Kennedy move next door to Daniel):
http://www.tthfanfic.org/Story-8752/DaveTurner+Early+One+Morning.htm -- REQUIEM FOR DAWN series by DaveTurner (very sad, but Buffy/Jack at the end):
http://www.tthfanfic.org/Series-145 -- A BRANE OF EXTRAORDINARY WOMEN series by DianeCastle (very entertaining multi-cross multi-'verse series, crossing and recombining the heroes and villains of HP, BtVS, SG1, Batman, The Secret Life of Alex Mack, and even the original Bionic Woman, with a surprisingly addictive and extra-lengthy third installment that has led to a wealth of spin-off fanfics itself):
http://www.tthfanfic.org/Series-2585 -- XANDER AND YET ANOTHER DEMON series by DianeCastle (very entertaining! Xander/Anise/Freya):
http://www.tthfanfic.org/Series-2591 -- THREE CORN FED FARM BOYS by DireSquirrel (very entertaining short fic, also crossed with Superman; Cam Mitchell, Riley Finn, and Clark Kent at their college reunion in Kansas):

http://www.tthfanfic.org/Series-7 -- THE GIFT OF A FAMILY series by FireDragon (Buffy as Jack's daughter; only the first story in this series is finished, and the writing can be very un-beta'd at times):

http://www.tthfanfic.org/Series-164 (chapter 8 of the unfinished 3rd story was only posted on her LJ in 2006:

http://www.tthfanfic.org/Story-28697/HMaxMarius+Infinity+Box.htm -- DAWN'S NEW JOB by IndraLeigh (badly in need of spell-checking and even a cursory proof-reading, but some cute lines now and then):
http://www.tthfanfic.org/Story-6093/IndraLeigh+Dawn+s+New+Job.htm -- FAR BEYOND NORMAL series by jAkL (3rd story is an unfinished cross with all incarnations of 'Star Trek', as well, but the first two stories are pretty straight SG1/BtVS and totally complete in themselves):
http://www.tthfanfic.org/Series-685 -- SGA fic THINGS WE TRADE FOR FREEDOM by JediButtercup (Faith/Ronon; after the Alterans reclaim Atlantis, Ronon chooses to accompany Sheppard to earth, and the two of them go on a road trip just in time to give Faith a lift to Sunnydale and help battle the First Evil):
http://www.tthfanfic.org/Story-26663/jedibuttercup+Things+We+Trade+For+Freedom.htm or
http://archiveofourown.org/works/296283?view_adult=true -- SEE FOR YOURSELF by JediButtercup (Dawn/mini!Daniel; Loki had cloned both Jack AND Daniel, so original!Daniel knows just who to send to check up on reports of strange, cult-like doings at a High School in California ... and the two teens with decades of experience find themselves way out of their depth, between the Summers sisters and the First in the final days of Sunnydale):
http://www.tthfanfic.org/Story-12923/jedibuttercup+See+For+Yourself.htm -- RING OF THE GODS series by JediButtercup (four collections of drabbles, mostly, with a very extensive one-chapter final story; Buffy/Cam Mitchell):

http://www.tthfanfic.org/Story-10629/jedibuttercup+Starting+Over.htm, or
http://archiveofourown.org/series/1567, or
http://jedibuttercup.livejournal.com/tag/s%3A%20starting%20over -- AN UNEXPECTED GIFT by Jedibuttercup (Spike's amulet sent to the SGC by Riley, intercepting the attempt to send it back to W&H, and only Daniel and Graham Miller can see and hear Spike; marked complete at 9 chapters, but was supposed to be the first in a series which hasn't materialized since 2006, so far; ends with Spike going off-world for the first time to avoid interference from Kinsey and Angel):

http://www.tthfanfic.org/Story-17630/JoeB+Nightmare+Revisited.htm -- SHE MEANT EVERYWHERE! by JoeB (Potentials are activated throughout the galaxy, so Buffy et al try to help the SGC help the new Slayers; not quite finished, but Burmafrd/Burmafrdnow has written a very satisfying coda on fanfiction.net,
Gods and the Champions They Like, so can be read as complete, in a sense:
http://www.tthfanfic.org/Story-4485-11/JoeB+She+MEANT+Everywhere.htm -- JUST A QUICK MISSION by Joshlamont (very amusing multi-cross, with Rory Gilmore as a Slayer infiltrating the SGC and bringing the Scoobies into conflict with the Goa'uld):
http://www.tthfanfic.org/Story-21616/joshlamont+Just+a+quick+mission.htm -- COUNTERPARTS. THEN COUNT 'EM AGAIN series by Joshlamont (SG1 keeps encountering Scoobies, first off-world, and then on, and then the wizarding world of HP gets thrown into the mix in the 3rd story. Skip the 4th one, which just focuses on the 'adventures' of the Goa'uld parasite who tried to take over Willow in the first story):
http://www.tthfanfic.org/Series-1988 -- KELLEY'S HEROES by jrabbit (Faith and Gen. Hammond get stranded off-world but show up in the nick of time to foil an attempt to open the hellmouth):
http://www.tthfanfic.org/Story-12734/jrabbit+Kelley+s+Heroes.htm -- OVERLAP series by Justaguy (Riley-centric -- 3rd and 4th stories should be read in reverse order):
http://www.tthfanfic.org/Series-548 -- TRICK OR TREAT by Kei (Xander turns out to be anathema to Goa'uld symbiotes, gets taken in for 'testing' at the SGC, tries to keep knowledge of his little Slayers out of the wrong hands, and manages to thumb his nose at the plans of the PTB in the end, while still helping out his new friend Jack O'Neill in the battles against the Goa'uld; no bashing of any Scooby at all, which is a delightful and refreshing change, and this is NOT a "Super-Xander" tale -- merely an understanding, insightful, emotionally evocative, and slightly imperfectly proof-read saga):
http://www.tthfanfic.org/Story-4301/Kei+Trick+Or+Treat.htm -- A HACKING GOOD TIME by Kei (humorous one-shot: Willow the hacker saves the world):
http://www.tthfanfic.org/Story-4965/Kei+A+Hacking+Good+Time.htm -- NOT ANOTHER KIDNAPPING by Kei (another humorous one-shot -- well, as humorous as Dawn being tortured by an ill-fated Goa'uld while waiting for Faith's inevitable rescue can get, all under the stunned gaze of SG1):

http://www.tthfanfic.org/Story-9997/LadyVulcan+To+see+is+to+disbelieve.htm -- CONTACT series by LiastraLee (Dawn/Jonas Quinn, with "Roswell" crossover joining the party after the initial story; good, meaty series, with some serious length stories as well as one-shots):
http://www.tthfanfic.org/Series-797 -- PATCHWORK ARC series by LisaRoquin (slashy SG1/BtVS crossover only available in web archive copies now; Xander/Daniel):
http://web.archive.org/web/20090616125434/http://www.tthfanfic.org/Series-40 1)

http://www.tthfanfic.org/Story-8374/Lisette+Godless+Provenance.htm -- MAGICAL CAGE series by litgal (only the two-chapter humorous sequel set in Sunnydale is slightly Spike/Xander slashy at times, and the main story is also quite good . . . if in need of more proof-reading):
http://www.tthfanfic.org/Series-425 or
http://litgal.brinkster.net/MagicalCage/1.htm -- AIRMAN HARRIS by litgal (sweet Xander/Daniel slash, but also offers a very insightful and hopeful alternate version of the last half of BtVS season 5, with some great moments of Buffy learning from and impressing the heck out of Jack, as one commanding officer to another, and Xander getting some pretty good PTSD counseling):
http://www.tthfanfic.org/Story-27088/litgal+Airman+Harris.htm or

http://www.tthfanfic.org/Story-17236/NotJana+Dawning+Familiarity.htm -- TEAL'C'S WISH by Nycorson (technically complete, but it ends where season 9 of SG1 ended, with a cliffhanger regarding the big picture as the Ori bring their armies into this galaxy, though Xander and Faith and the gang are all in a good place emotionally):
