Buffy the Vampire Slayer comics
Buffy the Vampire Slayer comics refer to comic books based on the television series Buffy the Vampire Slayer. While many of these comics were published when the television show was on air they are not all considered canonical and often deal with characters who do not appear on in the television series, most notably in the Tales of the Slayers and Tales of the Vampires mini-series.
The books were published by Dark Horse Comics between 1998 and 2004, originally in comic format but then gathered into volumes of trade paperbacks. A small number of Buffy comics have not been included in trade paperbacks, such as the books entitled "Giles", "Jonathan", and "Reunion".
Relation to the TV series
Series creator Joss Whedon and a number of writers involved with the television series authored many of the comic books. Overviews summarizing the comic books' storylines were written early in the writing process and were 'approved' by both Fox and Joss Whedon (or his office), and the books were therefore later published as official Buffy merchandise.
