The Complete Stephen King Encyclopedia: The definitive guide to the works of America's Master of Horror, by Stephen J. Spignesri (oversized TPB, 1991, 780 pages, $6)
Included here are articles:
about Stephen King and his work,
about his fans, collections and conventions,
about his newsletter,
on his motion picture adaptations,
and on his poetry.
There are-
interviews with the people that knew him,
and an index-
of the first lines of his works,
of his published works,
of his unpublished works,
of his characters,
and an annotated bibliography.
The scary part for me is that all this "complete" stuff ends here in 1991, so a whole other 780 page book could be written about Stephen King and his works. That's a lot of words. Is he worth it? Yup, in my opinion, and I don't even read his stuff.
Look for this book on the new non-fiction table. (L-SK area)
