This open access book presents fresh archival evidence to explore the underexamined manuscript cultures of girls living in Britain in the late nineteenth century.Girls were keen writers during this period, which witnessed Golden Ages of children's literature and journalism, as well as major developments in proto feminism.Girl writers were particularly prolific in the writing of manuscript magazines.These were handmade magazines in which the contributors were also the readers and subscribers.This book presents three case study chapters exploring manuscript magazines which were created and exchanged amongst girl-led writing groups and within families, and references many other examples of manuscript magazine cultures from the late-Victorian period.It argues that strategies of transformative writing—namely appropriating literary texts—often characterized girls' contributions to manuscript magazines.
