I'm just glad you're still doing this! We all really appreciate the work you're putting into this, and without your scans, I'd never know what the inside to the Panzer Dragoon Saga manual looked like... or Magic Knight Rayearth, for that matter 
I'm glad I can share my collection and be a source. I'm not one for advertising much, but hopefully someone looking for a manual for their loose copy of a Sega CD, Sega Saturn or Sega Dreamcast game will stumble upon the site and be able to check out the manual. If anyone feels like sharing this thread with any gaming sites they frequent, feel free. Perhaps it will lead to more scans from others noticing the site for the first time

I'd like to see someone try and tackle manual scans for Sega Master System, or NES, or even SNES or Genesis. I know those last two have quite a few releases, from my quick research, less than 800 each when looking at US releases alone. Those numbers can sound intimidating, but, once I finish all of my Sega manuals, that will put me around 650 manuals scanned, so it's definitely do-able, be it one person or a team. Though, with one person, you do get a level of consistency in how all manuals would look, which I think goes a long way.
A quick note on my SegaCD scans. Looking over the scans at SegaFans (that I linked to earlier), some are a bit rough (like their version of Wonderdog, which I uploaded to ratigators.com here this morning). So, I'll keep sharing my SegaCD scans as an alternate source. Plus, I went ahead and scanned in the "red" version of Wonderdog, as they had the "green" version.
I may come back around after the fact and fill in a few alt manuals, such as the "green" Wonderdog, the matte (not foil) Lunar, and the small Ecco, Sonic, and Sewer Shark manuals (from when they became pack in games), and the blue box version of Night Trap (this is the version that SegaFans has). Also, my scan for Rise of the Dragon will be the blue longbox re-release version (same as SegaFans). I have the original cardboard box release, though, it's still sealed. If I pick up an alt copy, I'll scan that in as well.
A minor annoyance with the SegaCD scans is that there are quite a few manual sizes, so I can't as easily run a batch. There's the original size manuals for the cardboard box released games (such as Wonderdog). Then there is the larger size from the jewel case releases, some which are even slightly wider than others (such as Eternal Champions and Wing Commander, 2 of the larger manuals). Then, the later box releases of the Digital Picture games (such as Corpse Killer) have even larger manuals. Then you have the manuals for the pack in games, such as Sol Feace and the original Sherlock Holmes that are their own custom size (not even a standard CD case size like the Dreamcast manuals). Finally, you have a one off like Colors of Modern Rock that is much smaller than anything else, much smaller than Dreamcast sized manuals.
