'The American careers of Ada Cambridge, Rolf Boldrewood and Rosa Praed all extended into the first decade of the twentieth century, with new titles appearing alongside reprints of earlier works. Other authors whose careers in the US market began before the turn of the century but extended well beyond it include Fergus Hume, Guy Boothby and Carlton Dawe. Although forty years separate the birthdates of the oldest and youngest of these six authors, they were largely contemporaries in terms of their American publishing careers, with the majority of all their US titles appearing between 1890 and 1910. Yet to shift focus from the first to the second group is to find oneself in a changed literary space, marked by the emergence of the modern genre system on both sides of the Atlantic and hence in the Australian literary marketplace as well. As writers and readers, colonial Australians were subjects not only of the British Empire but also of a transnational Anglophone market for popular entertainment, not least for popular fiction. They participated in an expanding mass market, and not merely a contained and containing colonial system.' (Introduction)
