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.
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.
