"For Tolkien, the word came before the world. Yet his claim that he created Middle-earth to house his invented languages has served mainly to raise sceptical eyebrows. The on-going publication of his writings on the languages and scripts of his sub-created world must remedy this...."
My review of Parma Eldalamberon 13 (The Alphabet of Rúmil & Early Noldorin Fragments) and 14 (Early Qenya & Valmaric), containing work by Tolkien on his Elvish languages and scripts mostly from the early 1920s, is now on my website:
The review was previously only available in Tolkien Studies 2 and via subscription-only Project Muse.
My aim is not to analyse the linguistic content but to show, for a general audience, why it has literary value and how it underpinned Tolkien's entire creative project.
I hope you will find it of interest.
