Banjo_oz: Obviously, the next question is... would you be able to scan your copy of the newspaper? :) I don't think it's ever been scanned online (certainly not at ReplacementDocs) and I hate the thought that any of these great "bits and pieces" of game fiction get lost in time without preservation!
eriktorbjorn: I don't know for sure. I might be able to, but I wouldn't feel comfortable distributing it since I don't hold any rights to it. If someone from GOG were to say, "Why, yes, we do have the right to distribute it, we just haven't been able to find any copy of it," that would be a different matter of course. But I don't even know if that sort of thing ever happens.
Of course, that's your call, but I personally don't think a piece of documentation would be an issue.
If it wasn't for generous collectors, scanners and sites like Replacementdocs, *many* fantastic documents would be lost (and I know many of GOG's manual scans originated in just such fan-preserved sources). Awesome things like Space Quest III's "Two Guys" punch-out glasses/snout would be lost forever if not for those few who own them keeping, scanning and preserving them, in many cases long after the original rights holders didn't even care about the game itself anymore.
IMO, the whole concept of "abandonware" is a very grey area, but I would be shocked if anyone aside from the most litigious of publishers (one does spring to mind!) were worried about an old manual or poster being scanned. Again, though, that's just my personal feeling.
Regardless, I'd be most surprised if GOG wasn't interested if you offered to scan the newspaper for *them* to include with their extras, if you still felt worried about posting it for free.
