The series' fiction has been officially expanded and elaborated on by authors and artists in the so-called "Buffyverse [[Expanded Universe]]". The creators of these works may or may not keep to established continuity. Similarly, writers for the TV series were under no obligation to use information which had been established by the Expanded Universe, and sometimes contradicted such continuity.

[[Dark Horse Comics|Dark Horse]] has published the [[Buffy the Vampire Slayer comics|''Buffy'' comics]] since 1998.<ref>"[http://www.darkhorse.com/Comics/98-372-a/Buffy-the-Vampire-Slayer-1-photo-cover Buffy the Vampire Slayer#1] {{Webarchive|url=https://web.archive.org/web/20151106211629/http://www.darkhorse.com/Comics/98-372-a/Buffy-the-Vampire-Slayer-1-photo-cover |date=November 6, 2015 }}" ''Dark Horse Comics'' ("Buffy the Vampire Slayer #1" released September 23, 1998).</ref> In 2003, Whedon wrote an eight-issue miniseries for Dark Horse Comics titled ''[[Fray (comic)|Fray]]'', about a Slayer in the future. Following the publication of ''[[Tales of the Vampires]]'' in 2004, ''Dark Horse Comics'' halted publication on Buffyverse-related comics and graphic novels. The company produced Whedon's ''[[Buffy the Vampire Slayer Season Eight]]'' with forty issues from March 2007 to January 2011, picking up where the television show left off—taking the place of an eighth [[canon (fiction)|canonical]] season.<ref name="ew-firstlook" /> The first story arc is also written by Whedon and is called "[[The Long Way Home (Buffy comic)|The Long Way Home]]", which has been widely well-received, with circulation rivaling industry leaders [[DC Comics|DC]] and [[Marvel Comics|Marvel's]] top-selling titles.<ref>{{cite web |url=http://comicsbeat.com/dc-comics-month-to-month-sales-april-2007/ |title=DC Comics Month-to-month Sales: April 2007 |date=June 5, 2007 |access-date=June 4, 2007 |publisher=The Beat |archive-date=May 13, 2014 |archive-url=https://web.archive.org/web/20140513011617/http://comicsbeat.com/dc-comics-month-to-month-sales-april-2007/ |url-status=live }}</ref> After "[[The Long Way Home (Buffy comic)|The Long Way Home]]" came other story arcs like Faith's return in "[[No Future for You]]" and a ''Fray'' crossover in "[[Time of Your Life (Buffy comic)|Time of Your Life]]". Dark Horse later followed ''Season Eight'' with ''[[Buffy the Vampire Slayer Season Nine]]'', starting in 2011, and ''[[Buffy the Vampire Slayer Season Ten]]'', which began in 2014. Dark Horse continued to publish ''Buffy'' comics continuing the story after the television show until September 2018, when it released the final issue of ''[[Buffy the Vampire Slayer Season Twelve]]'', which intended to bring closure to the series. Following the end of Dark Horse's ''Buffy'' series, [[Boom! Studios]] acquired the license to publish ''Buffy'' comics. Taking a different approach from Dark Horse, Boom! Studios decided to publish a new [[Buffy the Vampire Slayer (Boom! Studios)|rebooted ''Buffy'' series]] in 2019 with many elements updated to be more contemporary. Boom! Studio's approach to rebooting ''Buffy'' has been stylistically compared to the ''[[Ultimate Marvel]]'' series by the creators.<ref>{{cite web |url=https://comicbook.com/comics/2019/01/23/buffy-the-vampire-slayer-interview-jordie-bellaire-jeanine-schaefer/ |title=interview with Jordie Bellaire and Jeanie Schaefer |publisher=ComicBook.com |first=Jamie |last=Lovett |date=January 23, 2019 |access-date=April 21, 2019 |archive-date=April 21, 2019 |archive-url=https://web.archive.org/web/20190421201505/https://comicbook.com/comics/2019/01/23/buffy-the-vampire-slayer-interview-jordie-bellaire-jeanine-schaefer/ |url-status=live }}</ref> Joss Whedon is not as involved in the rebooted ''Buffy'' comic as he was in Dark Horse's continuation, however he did take part in the initial development stages for the series and gave his blessing to the creators.<ref>{{cite web |url=https://www.ign.com/articles/2019/01/23/why-boom-studios-decided-to-reboot-buffy-the-vampire-slayer |title=Why Boom!

The most recent novels include ''[[Carnival of Souls (Buffy novel)|Carnival of Souls]]'', ''[[Blackout (Buffy novel)|Blackout]]'', ''[[Portal Through Time]]'', ''[[Bad Bargain]]'', ''The Deathless'' and ''One Thing or Your Mother''.
