reesetee C_b beat me to it: prolificacy. But it sure is a mouthful. Prolificness is also listed by OED (though tagged as obsolete) and prolificalness is tagged as rare, but prolificity is also listed.
I'm enjoying there being a proliferation of "prolific" nouns. :-) Jan 8, 2009
chained_bear OED says prolificacy. I have a hazy memory of seeing "prolificness" in print, but it may have been a dream. Jan 8, 2009
