Ellipsis in English Literature

Dr. Anne Toner, of the Faculty of English at Trinity College Cambridge, UK, studies varieties of incompleteness in literary works. She has recently published a book which focusses on a particular incompleteness signifier: Ellipsis in English Literature : Signs of Omission. The publisher notes :

Anne.TonerAnne Toner provides an original account of the history of ellipsis marks – dots, dashes and asterisks – in English literary writing. Highlighting ever-renewing interest in these forms of non-completion in literature, Toner demonstrates how writers have striven to get closer to the hesitancies and interruptions of spoken language, the indeterminacies of thought, and the successive or fragmented nature of experience by means of these textual symbols.”
