This brings up images of monastery monks in rows creating illuminated manuscripts and selling them to local lords.....I so approve. I have tried this before, the rub is the complexity of the books. Once you get the industries reliable for ink and glue and binding it should work well. Or you could add the ingredients as purchasable things in one of the shops and then increase the value for the book to balance out. Sorry to just blah on your thread, I just like the idea but am to busy/lazy to change it. (all my energy will be devoted to the possible upcoming humans addition). If you get it to work and are willing to share let me know.
