Given the centrality of London as a setting in English literature, interpretations and imaginations of the literary city have continually been re-written to incorporate new social norms. As the city expanded, concerns arose around the movement of women and children within the urban environment. These concerns around move- ment can also be found in literature for children and young adults. Research has shown that studies of space and place in literature are once again taking centre stage as an emerging technology in the Digital Humanities allows scholars to re-explore literary landscapes through digital maps. This dissertation demonstrates how pro- tagonist demographic elements of gender and age impact identity formation through movement in the London of fantasy youth literature. The variables of gender and age were chosen because I believe that children’s literature has a formative impact on its readers and I want to document the extent to which these texts either chal- lenge or re-inscribe dominant, oppressive hierarchies. In this context, children’s and young adult fantasy literature encompasses fantasy novels for children aged nine to twelve years of age as well as those for young adults ranging from thirteen to twenty years old. By means of digital mapping, sixty-six children’s and young adult fantasy novels have been geographically coded. Digital mapping provides the tools needed to close read texts which both follow and deviate from the well-travelled path. By digitally mapping fantasy literature for young people that is set in London, we can illustrate the most familiar areas of the city but also bring to light areas that continue to be shunned. This dissertation is situated at the convergence of literary geography, children’s fantasy literary studies and the Digital Humanities. As such, Chapters 1 and 2 introduce the personal and theoretical concepts which led to this thesis and include a literature review divided into four sections: mapping space and place, youth literature, fantasy, and Digital Humanities. Chapter 3 demonstrates the novel Digital Humanities methodology utilised to annotate, code and digitally map the sixty-six novels in this corpus. Chapter 4 examines the role of landmarks in the process of protagonist identity formation. Meanwhile, Chapters 5 and 6 each demonstrate the way in which age and gender impact identity formation via movement through London. This anal- ysis demonstrates the ways protagonists move through the City of London and explores the link between identity formation and digital literary geographies. This dissertation is intended as a contribution to scholarship on the intersection between youth literature scholarship and the Digital Humanities, an area of research still in its infancy. It also aims to enrich the critical conversation surrounding the use of Digital Humanities methodologies, especially on children’s and young adult texts, and particularly in relation to identity. Notably, it demonstrates the value of Digital Humanities methodologies for studying identity through movement in fantasy youth literature set in London.
