Also included in this volume is the lecture English and Welsh; the Valedictory Address to the University of Oxford in 1959; and a paper on Invented Languages delivered in 1931, with exemplification from poems in the Elvish tongues. Most famous of all is On Fairy-Stories, a discussion of the nature of fairy-tales and fantasy, which gives insight into Tolkien's approach to the whole genre.
The pieces in this collection cover a period of nearly thirty years, beginning six years before the publication of The Hobbit, with a unique 'academic' lecture on his invention (calling it A Secret Vice) and concluding with his farewell to professorship, five years after the publication of The Lord of the Rings.
This collection will appeal to you if you are any kind of devotee of medieval English literature. Even if Tolkien had never written his great fantasy novels, he'd be revered for his work in Old English, especially as a champion of the poetic reputation of "Beowulf," a poem he almost single-handedly wrested from historians and philologists and set in its proper place at the root of English literature.
He also makes an eloquent case for the essential connection between the study of language and that of literature. If you consider yourself a student of great writing, but have only read Anglo-Saxon poetry in someone's "translation," Prof. Tolkien will politely shame you out of complacency.
In his valedictory address, speaking as a native of South Africa, he says, "I have the hatred of apartheid in my bones; and most of all I detest the segregation or separation of Language and Literature. I do not care which of them you think White."
The book will also appeal to you if you have spent years immersed in the world of Middle Earth. Though there are scarcely any direct references to LotR in these essays, they illuminate the mind behind the masterpiece -- the quirky love of languages, the vision of fantasy as a godly act of creation, the deep Catholic faith.
Tolkien couldn't write a grocery shopping list without adding at least two appendices, as these essays prove, and some of the best gems are in the footnotes. His theories on the unconnectedness of drama and literature are also provocative and well-argued.
The production on this edition is a bit shoddy: it looks like the fonts were squeezed, there are some typos, and the paper quality is poor.
