Oh, dear... another thing they got seriously wrong. *sigh*
Web of the City (his first book) is in no way sff. It is a novel about gang kids in New York. It is alternately crude (as befits a young writer) and very good; not at all bad for a first novel, but there is no way it touches on sf save as metaphors for a description or two.
The Man with Nine Lives (
The Sound of a Scythe)
is a sff novel, but it's a fix-up novel of the original novella "The Sound of a Scythe" and a couple of other stories, plus some new material. Awkward, at times clumsy, but also with some very good moments. On the whole, a fairly typical sf "novel" (it is quite short) of the sort to be seen in the ACE double line, though featuring themes and motifs Ellison would revisit from time to time, most notably in "The Region Between".
A Touch of Infinity is his first sf story collection, the flip-side of the ACE double with the novel mentioned just above. The table of contents can be found here:
Ellison / A Touch of Infinity
In fact, that's a good site for any such information on Ellison.
Spider Kiss is a rock-'n'-roll novel based loosely on Jerry Lee Lewis (with quite a few other things thrown in), which incorporated an early Ellison story, "Matinee Idyll" (somewhat rewritten) as one of its core elements. Good book; some powerful stuff there, but not sff.
Doomsman -- another double; this one Belmont; originally released with
Telepower by Lee Hoffman, later re-released (much to Ellison's dismay) with Lin Carter's
The Thief of Thoth. (Ellison is
not a fan of Carter's fiction, to put it mildly.) It's an early story (1958), reprinted without Ellison's prior knowledge (iirc), and not one he's likely to allow to see reprint anytime soon. Very early Ellison; very crude. Yes, it's sf, but -- aside from a few moments or if you're interested in seeing Ellison's development as a writer -- I don't really think it's worth looking for....
Phoenix Without Ashes -- the
novel is by Ed Bryant, from Ellison's screenplay for the pilot of
The Starlost. An interesting book, not a sterling attempt, on the generational ship idea. The introduction is the only part of the book's text by Ellison though, of course, the entire structure and basis of the thing is his original award-winning screenplay.
Vic and Blood and
Harlan Ellison's Dream Corridor (of which there are two volumes) are "graphic novels"... or, rather, one is a graphic novel, while the other is a set of comic book adaptations of Ellison tales by different artists, with some new material added... much like The Illustrated Harlan Ellison of some years before. Even Vic and Blood is an adaptation of previously existing stories: "A Boy and His Dog", "Eggsucker", and "Run, Spot, Run", which are parts of a long-proposed novel called
Blood's a Rover.
So, really, the only thing they've got more-or-less right there is
The Man with Nine Lives... and even
that isn't a true novel in length; more a novelette....
