However, through notes and letters of Tolkien, a great deal of it published posthumously by his son Christopher Tolkien, as well as in passages from the Annals of the Kings and Rulers (An appendix of The Return of the King) and other portions of The Lord of the Rings and The Silmarillion, some events can be defined.
In The Return of the Shadow, Christopher Tolkien states that some time after the publication of The Lord of the Rings, his father "gave a great deal of thought to the matter of Glorfindel" in the book, and decided that it was a "somewhat random use" of a name from The Silmarillion that would probably have been changed, had it been noticed sooner.
