Tolkien's translation of the Beowulf Saga

On Slashdot I read that a new Tolkien book is discovered:

A YELLOWING manuscript by J.R.R.Tolkien discovered in an Oxford library could become one of the publishing sensations of 2003.

The 2000 handwritten pages include Tolkien's translation and appraisal of Beowulf, the epic 8th century Anglo-Saxon poem of bravery, friendship and monster-slaying that is thought to have inspired The Lord of the Rings.
