Authorship in the works of J. R. R. Tolkien is a subject of many facets. Within the mythology and history of Middle-earth, many story-tellers, bards, annalists and poets contribute to the weaving of an enormous tapestry of tales. Sub-creation, as Tolkien practiced it, involves an abundance of traditions, including different modes of authorship and literary creation - and some depart strikingly from the common modern notions. Instead of proposing a unified perception, the six articles in this collection therefore examine the web of authorial presence and authorship concepts in Tolkien's works from diverse angles, to trace a polyphonous dialogue between the writer of the texts and the many voices within that shape Middle-earth in concert.
