Well, with Troy and Moose's consent, I have now tagged each article by it's respective book. I've done this for various reasons: primarily organisation. When #WanderersLibrary has a bot dedicated to it, this will allow it to reference articles by book or list a specific Book's contents en masse. It also allows Wikidot to create automatically generated hub pages for ease of doing that on-site.
For example, if I want to simletaneously link all pages in the Book of Ur, I can do that like so.
