The Lost Books of Appendix N

Pushed into motion by the Appendix N Jam (find my entry here) I have engaged in an intensive, rigourous (and two-fisted) period of study, research and legwork looking into the early literary inspirations of D&D and have discovered a veritable corpus of lost works of fantasy fiction.
