So I am on a multiplayer server and once of the things I was is to give bookbinding a try and make a library. As part of this I have written some short in character "chapters" for my character's Memoirs. We also have the boardgame mod so I'll probably copy in some basic rulebooks for various games so people can learn in game to. I'll probably make some "prop books" too, titling them as references but not put much in them; The Necronomicon, The Silt Verses, The Book of Vile Darkness, The Book of Exhalted Deeds, The Voynich Manuscript, The Owl By Daylight by Philip K. Dick, The Declaration of Deeds, The King in Yellow, The Enchiridion, etc.
What about the rest of you who bookbind? Are you satisfied for them to be purely ornamental or do you write in them too? And for the ornamental ones what names do you go for? Maybe if people wanted to we could share them somewhere so people can copy into their own books and proliferate copies between worlds.
