Unfinished Tales
However, as it does not include information on post-"Silmarillion" material (i.e. "Unfinished Tales" and the series "The History of Middle-earth"), the 1978 edition contains some assertions contradicted by later publications. For example, the Star of Elendil jewel (Elendilmir) is identified with the Star of the Dúnedain given to Samwise Gamgee, but Christopher Tolkien refutes this. It also includes speculation on matters later confirmed in subsequent works. For example, Foster proposes that Gandalf and Olórin are one and the same – confirmed in "Unfinished Tales".
