What about allowing bookshelves, in castles, that can hold player-made books? Instead of wizards having to hard-code books submitted by Garkin, how about players being able to buy "blank books" (like the blank scrolls that exist) and players can write in them. Perhaps allow functionality for adding pages, where each page acts a bit like scrolls do now. And perhaps make a way to duplicate them (perhaps at a cost...Gutenberg comes to Darke) so that books can be distributed...for free, as a saleable item (if any of us are good enough writers that people would pay mcgrail to read what we produce), whatever.
