Who here knows a lot about Mythlore? Or who I can talk to about it?

More specifically, I want to:

* find out how close these two are in terms of content:
o "Christensen, Bonniejean. "Tolkien's Creative Technique:
Beowulf and The Hobbit." Mythlore 15 (Spring 1989): 4-10.
o Christensen, Bonniejean. "Beowulf and The Hobbit: Elegy into
Fantasy in J. R. R. Tolkien's Creative Technique."
Dissertation, University of Southern California, 1969. DAI
30 (1970): 4401-02A.

* get a copy of the former (or, indeed, the latter!)

Any advice, help etc will be much appreciated!

Thanks
