Is Michael Moorcock considered science fiction or fantasy?  I have several volumes of his, and I've been told they are to be read in order, but not necessarily in the order they appear in the books (several books in one omnibus).  Has anyone read any of these, and are they any good?  The first one is The Eternal Champion and includes the books The Eternal Champion; Phoenix in Obsidian; and The Sundered Worlds.  And then there's about 12 more volumes, I think.

I put this in the Fantasy forum as well, but I thought maybe I should put it in both places.  And since I am not exactly sure what the difference between fantasy and science fiction, I didn't know the proper place for it.

See my topic.  I have 12 of Moorcock's books on my shelf, there all since last August with no takers.  Let me know if any interest---search my shelf.  Any reasonable deal is acceptable, starting at 3 for 2, but will negotiate.  Thanks.
