"The Tolkien Reader" is an excellent collection of shorter writings by the Lord of the Rings author. Each of the pieces here represent a different genre - drama, essay, short fiction, and poetry - that are, for the most part, unrelated to Middle Earth, but if you've read The Hobbit and/or LOTR and aren't sure what to read next, this is a great place to start.
The Reader opens with "Tolkien's Magical Ring," a short preface by Peter S. Beagle, who is best known for his novel "The Last Unicorn." Fans of Tolkien might be tempted to skip over this, since Beagle spends most of it summarizing the story and themes in The Hobbit/LOTR. I'm really glad I didn't pass it over, though, because Beagle has nothing but the utmost admiration for Tolkien and there are some stunning lines. My favorite: "Old friends rediscover it, as I do... and we talk of it at once as though we had just read it for the first time, and as though we were remembering something that had happened to us together long ago. Something of ourselves has gone into reading it, and so it belongs to us." Later, he adds, "I believe that Tolkien has wandered in Middle-Earth, which exists nowhere but in himself, and I understand the sadness of the Elves, and I have seen Mordor." I've never read any of Beagle's fiction, but this brief essay alone makes me want to pick up "The Last Unicorn."
The first Tolkien-penned work in the Reader is "The Homecoming of Beorhtnoth Beorhthelm's Son," a one-act historical drama based on a battle fought between the English and the Danes in the 10th century. The drama itself is not particularly interesting; it's primarily a conversation between two characters as they search for the body of their fallen king in the aftermath of the battle. I was more interested in the two short essays that accompany this work to explain the historical background and themes. The idea of chivalry - and whether it's possible to be too chivalrous - is discussed in the second essay, and the influences of Anglo-Saxon culture on LOTR are quite obvious here.
Next is "On Fairy-Stories," which is probably the most important and interesting work in the Reader. If you can only read one piece in this anthology, it has to be this essay. Tolkien discusses the origins of fairy tales, how he believes they should be defined, who they are intended for (and who they *should* be intended for), and then broadens the scope of the essay to discuss the genre of fantasy fiction as a whole. The essay is long, dense, and wordy, in typical Tolkien fashion, but it sheds a lot of light on how Tolkien views fantasy. My favorite section of the essay is towards the end when he criticizes those who say that fantasy is a "lesser" genre because it is an escape from the problems of our world - and an unrealistic escape at that: "Fantasy can, of course, be carried to excess. It can be ill done. It can be put to evil uses. It may even delude the minds out of which it came. But of what human thing in this fallen world is that not true?"
Following Tolkien's essay is "Leaf by Niggle," a short story about a painter named Niggle. There are a couple of different ways to read this story; I prefer to interpret it as an allegorical tale about the creative process Tolkien undergoes when working on fiction. This is probably my favorite piece of fiction in the Reader.
After "Niggle" is "Farmer Giles of Ham," a story about a farmer named Giles who is tasked with slaying a dragon named Chrysophylax. It's easy to compare this story to The Hobbit, because at first glance the plots of both seem very similar (Giles and Bilbo are also cut of the same cloth). But Farmer Giles is much more of a lighthearted story, and Chrysophylax and Smaug are different characters. Very enjoyable and entertaining.
Finally, we have "The Adventures of Tom Bombadil," a collection of 16 poems from Middle Earth. The title of this section is deceiving; only two of the poems are about Tom Bombadil. I thoroughly enjoyed every single poem (some of which previously appeared in LOTR), especially "Princess Mee" and "The Sea-Bell." Additionally, if you haven't read The Hobbit or LOTR, the poems are still easily accessible because they don't directly reference any of the events in those works.
All in all, this is a fantastic anthology of Tolkien's writing. Apart from the essay, none of the pieces in the Reader are particularly long, so it's easy to read a story or poem here and there without feeling obligated to finish the entire collection (with that being said, I did read this in just a few days because I loved the stories so much). Recommended for anyone who appreciates Tolkien, whether you've read LOTR or not.
