I have a number of books that are too difficult for me to edit without destroying the quality. If anyone is interested in these books and is able to produce a good looking raw, feel free to PM me and I can share the scans. Everything here is touhou except the last one.
@qazmlpok: I would just share the files as they are, if you can't really do anything to improve. If someone wants to work on something, they'll figure out how to do it themselves. My 2 cents.
@Juggernaut Santa Most of these haven't been uploaded, and it's more of a pain to do so these days since mega reduced their free account limit to just 15gb. A handful also had bounties available, where they either got no attention or had a few people attempt but throw in the towel because they couldn't get it to look nice either.
