Often, while browsing the Internet, I come across something in reference to Lord of the Rings and on googling it, it's something that I don't know about. I've seen the movies and am currently reading The Hobbit.
I was wondering about are there any other publication out there written or otherwise? If yes, could you be please be so kind as to help me with the chronological order of them.
The ones that I'm aware of are The Silmarillion, The Hobbit and the Lord of the Rings trilogy books (and the movies of course).
EDIT:
Yes, the answers here cover a lot about the query. But it seems like the content of the mentioned publication is mostly about Middle Earth. I was hoping to know not just about the publications related to The Lord Of the Rings, rathar more about the history of other landmasses and other peoples. For Example: today I came across Yearsof the lamps, Years of the Trees. Having not read all the known (to me) publications I wasnt sure whether how much of these and other things, that I'm not aware of, are covered.
Thanks to DevSolar, for mentioning Unfinished Tales of Middle-Earth. Not sure if these publication are the all that cover the full extent of the matter.
