Manuscript of the "Tale of the Years"

The Tale of Years" is a chronological list of the same sort as that in Appendix B to The Lord of the Rings. It exists in different forms, associated with the earlier and later Annals of Aman.
C. Tolkien noted: "{it} is perhaps the most complex and difficult text of all that my father left behind him. This need not concern us here." And he decided to not published it in full in HOME X. This is very unfortunate.
