Here are cover images of some of the Bewitched-related books I've seen around. The first and newest item on this page
is Adam-Michael James's compendium of all 254 Bewitched episodes. The second one shown below is the
third edition, which you can probably find at a bookstore near you. The cookbook (out of print) you may still be
able to find as well. It was co-written by Kasey Rogers, who played Louise Tate on the show.
