Okay, got it. So: "No more than 1/3 of any single self-contained story, even if that story is part of an anthology. No more than 1/3 of any singly published trade, anthology or graphic novel, even if that work is part of a longer storyarc." Sound right?
I'd tend to agree with others that no more than 1/3 of a story in an anthology is near unworkable; I can get the gist of 22 pages from 7, but 6 from 2 is a lot less functional. As a poster, I wouldn't even bother unless it was to point out a single joke or a nice bit of art. We sold a lot of people on the DC Christmas special last year; I wonder if even half of them would have thought it was worth it if they hadn't been able to read a single story.
(Beyond that, I gotta confess, I don't think we can honestly shave the rules to a point where we satisfy fair use, legally, and are still anything like the S_D we were before... which is before you consider that even if we are fair use, are we genuinely going to try to take it to court if Marvel challenges us? Will we even have the chance, or is IJ just going to fold over the way LJ did at the mere threat of litigation? There's a reason there's never been a legal test case for fanfic, and FFnet just chooses not to host the works of certain authors. I'm not saying we shouldn't make an effort to make it clear we respect the industry we've formed around, but I do wonder if we shouldn't still simply *accept* that we're doing something on the edge of the law and there's an extent to which we simply can't protect ourselves if the big guys decide they really care and therefore shouldn't maim ourselves trying.)
