You might want to check out Re/Search's issue called "Incredibly Strange
Films."  There are interviews with some "major" directors (Steckler,
HG Lewis, Russ Meyers) and some great short articles on oddball genres
(biker films, "mondo" films).  There's lots of other stuff.  It ain't
exactly B (more like Z) but there's some fun stuff in there.
