New links

Under "fiction," I've added a link for John Steinbeck, to a Paris Review compilation of his thoughts on writing (a free download).

Under "poetry," the Marianne Moore link now goes to her Paris Review interview (another free download).

Under "writing and tools," I've added links to the Cool Tools site and to a page that explains what became of the Blackwing pencil, Steinbeck's favorite pencil.
