With a few changes Wurm could have writers, publishers and bookshops!
Let us write question marks, line breaks and other characters on papyrus and paper sheets.
When a book page is renamed, use that name. So instead of "inscribed paper sheet, walnut (Introduction)" it just says "Introduction". This already happens with the book title.
Allow more books on bookshelves. 11 (low bookshelf) and 15 (high bookshelf) look a bit pathetic.
Let merchants sell books with pages.
Some of these suggestions have already been made in other threads.
