Dracula has been attributed to many literary genres including vampire literature, horror fiction, the gothic novel and invasion literature. Structurally it is an epistolary novel, that is, told as a series of diary entries and letters. Literary critics have examined many themes in the novel, such as the role of women in Victorian culture, conventional and conservative sexuality, immigration, colonialism, postcolonialism and folklore. Although Stoker did not invent the vampire, the novel's influence on the popularity of vampires has been singularly responsible for many theatrical and film interpretations throughout the 20th and 21st centuries.
Dracula is one of the few horror books to be honored by inclusion in the Norton Critical Edition series. (The others are Frankenstein, The Turn of the Screw, Heart of Darkness, The Picture of Dorian Gray, and The Metamorphosis.) This 100th-anniversary edition includes not only the complete authoritative text of the novel with illuminating footnotes, but also four contextual essays, five reviews from the time of publication, five articles on dramatic and film variations, and seven selections from literary and academic criticism. Nina Auerbach of the University of Pennsylvania (author of Our Vampires, Ourselves) and horror scholar David J. Skal (author of Hollywood Gothic, The Monster Show, and Screams of Reason) are the editors of the volume. Especially fascinating are excerpts from materials that Bram Stoker consulted in his research for the book, and his working papers over the several years he was composing it. The selection of criticism includes essays on how Dracula deals with female sexuality, gender inversion, homoerotic elements, and Victorian fears of "reverse colonization" by politically turbulent Transylvania.
