J.R.R. Tolkien was an Oxford educated scholar and published many pieces of academic works. For the purpose of this guide I have included translations of mythological works as academic endeavors as opposed to fictional stories. This list focuses on the texts produced in which Tolkien was the primary author or editor.
- A Middle English Vocabulary (published in 1922)
- Sir Gawain and the Green Knight (co-edited by J.R.R. Tolkien and E.V. Gordon, published in 1925)
- Songs for the Philologists (by J.R.R. Tolkien, E.V. Gordon and others, published in 1936)
- Beowulf: The Monsters and the Critics (published in 1937)
- Sir Orfeo (published in 1944)
- Middle English 'Losenger': Sketch of an etymological and semantic enquiry (published in 1953)
- Ancrene Wisse (edited by Tolkien, published in 1962)
- The Letters of J.R.R. Tolkien (edited by Christopher Tolkien and Humphrey Carpenter, published in 1981)
I have purposely decided to leave the History of Middle-Earth series (edited by Christopher Tolkien) out of this selection of texts because, while it is non-fiction and academic in its nature it is heavily related to middle earth it seems more appropriate to relate it in the fiction section rather than academic works.
