When Ed had exhausted his opportunities in mainstream Hollywood, it's a well-known fact that he went on to work on the seedier side of town; exploitation, soft-core and, eventually, hard-core pornographic movies. Less known is the fact that Ed wrote many exploitation novels at this time. In fact, he was so prolific it was in all liklihood his writing that really kept him afloat at this time, as his work in movies could never have amounted to enough to get by.
His work in this field was apparently, in part, set up by his friend Stephen Apostolof (with whom, of course, Ed made several films). They run the gamut from lesbian sex to the Watts riots.
Additionally, Ed often contributed to magazines and other publications. There were the occasional legitimate publications, but most are for magazines from the same publishers he wrote novels for. He also occasionally sent in articles to adult movie magazines promoting his films.
The three sections below cover all identified Ed publications. The "Other Writings" section covers anything that just isn't quite a magazine or book. Books, articles and other publications about Ed can be found on the Miscellany page.
