This chapter concerns changing patterns of serial publication, a term which covers two related practices: the publishing of periodicals with miscellaneous contents, including both magazines and newspapers, and the issuing of unified texts at intervals in independent fascicles or parts. Piecemeal publication blurred generic distinctions between news and fiction, but also between new print, revised print and reprint editions, and between serialisation, book, sequel and series. Publication of original novels in fascicles lost ground in the face of the new wave of literary miscellanies, whether monthly or weekly, which sold at lower prices once knowledge taxes were abolished and mechanical improvements cheapened book production and distribution. Primary developments in serialisation included both the expansion of the mass periodical and newspaper market and the segmentation of the market into diversely identified readerships. The chapter discusses the long-anticipated demise of the multi-volume first edition in the mid-1890s and the regulation of price discounting through the Net Book Agreement established in January 1900.
