I'll make this brief: I've looked around, and there doesn't appear to be any convention for uploading new books to the Library and Index. While I've no doubt that uploading new articles without contriving to ask permission is acceptable, the creation of new books seems a much greater alteration. As such, I decided to err on the side of caution, which is why I'm now asking any mods, admins, or simply anyone who knows exactly what proper channels, if any, exist for this sort of thing.
