The new CatScan is (IMHO) very unfriendly, you may find the old one more usable. Main page for all versions: http://en.wikipedia.org/wiki/Wikipedia:CatScan
(3) A third option which will pick up names of articles (but no further details) is this category search tool:http://toolserver.org/~magnus/catscan_rewrite.php which lets you enter a category and search several layers deep. So nested categories will show up. Try entering "Novelists" under "categories" and "3" under "depth".
