This thesis is a compilation of four articles concerning various aspects of intertext, intertextual practice, and various ‘goings-on’ of fandom. Specifically this thesis concerns the folklore of Discworld fandom as expressed in the annual celebration of Hogswatch in Wincanton, Somerset, through the eyes of a folklorist. The general aim of this thesis is to explore a specific fandom celebration – Hogswatch in Wincanton – using methodology and theory prominent in folkloristics. The first article is an analysis of the intertextual and contextual construction of fandom in the celebration in Wincanton. This is where I outline the ideas of intertext and intertextual common sense, drawing upon folkloristic, intertextual scholars. The second article is a study of the mercantile part of fandom, through the notion of gift-economy. The third article is a study of the use of narratives in the celebration, more specifically the staged narratives performed during the celebration. This is done by using the narratological concept of qualia. The last article is published in this volume. The article analyses the material manifestations of fandom culture (costuming and handicrafts) through the concept of folk art. The thesis main theoretical concepts, utilized throughout the article series, are the notions of folklore, fandom and intertext. The main concepts are discussed in the chapters preceding the articles. Also discussed is the field methodology issues of doing participant observation in affectively invested fields, alongside a thorough description of the ethnographic fieldwork. The thesis show how intertext permeates fandom culture and how by using the notion of intertext one can explore and investigate fandom-expressions of affect; performance events, trading, narrative and material expression. It also shows how using folkloristic methodology and theory and treating the expression of fandom as folklore makes it easier to contextualize.
