Out today!
A concise notice from Grantian Florilegium:

The Legend of Sigurd and Gudrun a previously unknown work by J.R.R. Tolkien was released today. Written more than seventy years ago, the story retells the epic legends of the Norse hero, Sigurd, the dragon-slayer, the revenge of his wife, Gudrun, and the Fall of the Nibelungs.

Introducing the work is one of Tolkien’s renowned lectures on Norse literature. Amazingly, no part of the story or the lecture has ever been reproduced or quoted from since they were first written.

Of course, the Norse legends and sagas were the single greatest influence on Tolkien’s writings, and many of the events in Sigurd and Gudrun can be traced through to The Hobbit, The Lord of the Rings, The Silmarrillion, and The Children of Hurin. No serious reader of Tolkien will want to miss this remarkable new resource.
