Cenobites in more than just Hellbound Heart?

Hello,
I remember somewhere in Hellbound Heart, there is mention of a book
exclusively about the Cenobites, a sort of Encylopedia or history, if
the name was any indication. This led me to believe Barker may have
written other books dealing with these characters.
This was further suggested when I recently watched the featurette on
Hellraiser, entitled Resurrection, where Barker says that he is almost
finished with the tale of the Cenobites, and how they phase out. This
interview was conducted in 2000. It seems like this tale would be out
there by now. Are these stories he is telling in those new graphic
novels? Are there any more novels or novelettes/short stories that
mention them? Any information will be greatly appreciated. Thanks!
