Welcome to PT. I do hope you enjoy your visits to our site.
I am not sure on what you require, exactly.
There are some great reference books that discuss Tolkien's works. Tom Shippey's JRR Tolkien: Author of the Century is a very good reference. For a biography, I prefer the one written by Humphrey Carpenter and The Letters of JRR Tolkien is invaluable. If you are interested in Tolkien's artwork, JRR Tolkien: Artist and Illustrator by Wayne Hammond and Christina Scull is an absolutely fabulous insight into Tolkien's world as he imagined it.
We have a biography on this site that was compiled by the Writer's Guild and these are some of the resources which we used.
You may also wish to check out the Tolkien Online Courses on this site. I use Tolkien's letters as a reference for most of the topics discussed.
For discussions and interpretation of The Silmarillion, take a look at the Silmarillion Reading Discussion Group.
I hope this is of some help.
