Buffy the Vampire Slayer

While many comic books based on the television series Buffy the Vampire Slayer were published when the television show was on air they are not all considered canonical and often deal with characters who do not appear in the television series, most notably in the Tales of the Slayers and Tales of the Vampires mini-series. The first series of 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"…Wikipedia
