- "For not we but those who come after will make the legends of our time. The green earth, say you? That is a mighty matter of legend, though you tread it under the light of day!"
- ― Aragorn, The Two Towers, "The Riders of Rohan"
The term of legendarium is not the same as "canon". The legendarium includes all Tolkien's corpus in its entirety, even mutually contradicting versions, both earlier and later stages of its conception.

 Other sources
More of Tolkien's vision of his legendarium can be found in interviews conducted with him. Hints of lesser value (i.e., hard to verify the authenticity), may also be found in reminiscences. There is also much material on the topic that remains unpublished, including many letters not published in The Letters of J.R.R. Tolkien.
