at first a few new buildings:
papermill: needs power, a serrated disc and any building material (wood, stone, metal)
libary: just a building material
a lot of new stuff:
paper: the basic stuff, made in the papermill with a bucket of water (well or river should be nearby) and a unit of wood, the buket will be empty and reusable of course
scrolls: a empty scroll can be created on the libary with one unit of paper
books: 5 paper or 5 empty scrolls and a unit of wood (cover) can be bind together as a book at the libary
bookcase: blacksmith/carpenter/mason/glass acts like a chest for books, bookcases can be made a libary too, its like a stature park another meeting area
a new skill: writing and a new job type libarian
so what can be done with them?
at first case it may be more interesting with the magics arc (or something)
but it could also be of use now:
bookkeeper, manager and broker in large fortresses may need books for their work and bookcases in their offices
this seems to be pretty clear, i dont think a bookkeeper cant hold up with the 10000 units of stone clutterin the shafts without a record keeping method beside his brain. also broker and manager will use a book or scroll to fill in their needs. the last two may need only one book for 5 years (or a scroll per year). the bookkeeper may need one scroll per 1000 units of stuff (so a book for 5000).
scrolls or books needed with this stuff will be called "stock scroll/book" for the bookkeeper, "manager scroll/book" for the manager and "trade scroll/book" for the broker, viewing such an item will show on the discription what stuff shows on what/which year/s it was used. for archelogic adventures another way to find out of the history of a fortress ^^
also the major or higher nobles will demand a scroll for diplomacy and trading aggreements in large fortresses, so no scrolls around: buy some from the humans or dwarfs or you will piss off nobles and ambassors ^^ so they also demand a book case in their rooms sooner or later to store the "aggrement scrolls"
dwarfs can use bookcases also in their private rooms, also a shop may get a book store and they buy some books.
this brings to the next tasks:
dwarfs with libarian skills my make the scrolls/books but more important they can write books
there should be two types of books: skill books and general books
the later may be "history books" or a novel ... depending on what a dwarf likes.
history books act like engravments, except for the fact it will be used more on legends and some artifacts, instead of most commonly the fortress itself (so exact the other way around engravings work). novels may act the same but instead they are discribing randomly generated never happened stuff. therefore are different types of novels (just to keep up with dfs detailism). all novels and history books of course only hold up one liners about the content.
"legend novel": they discribe things before year 0, so it is totaly unclear if it really happened about things you wont see in the legends, or is some dwarfen lore to keep children in line ^^
"romance novel": well it may or may not refer to a real lover pair in your fort, but at least its a novel
"adventure novel": it discribe about battles or heros never were in the world, or maybe refer to one great legend with a lot of fantasy of the writing dwarf. (like killing about 10 dragons but the real creature in lore only killed a single crocodile ^^). it may also refer to your adventure mode beings ^^
good writer make higher quality books, they can be encrusted with gems and stuff like other furniture
dwarfs may read a book in their "on break" or "idle" time from their personal bookcase or a book case in a meeting hall room (dining room, barrak, statue park, zoo, etc.), and thus it make them a happy thought, better books make happier thoughts, also i think its kinda fun if you get a fortress of your friend and discover it in adventure mode and find this books, and real them like engravings too ;p or just another way to buy things from caravans
the other thing is a skill book: a libarian ordered to make a skill book will follow a dwarf with the profession and write, depending on how good the one is in his profession and the writer himself the book get better quality. so a legendary writer following a legendary miner make some kind of masterfully crafted "how to mine" book ^^ encrusting and stuff make the books more expensive, but it doesnt affect a reader much.
this skill books will be stored in public book cases, dwarfs with idle time try to get a book from their skill, so they can improve their own with just reading (but not to high) also children will pick a book and learn from it, so they wont only be peasants any more than growing up (you better not let your libarian ever write a book about a soap maker
)
i dont know if v41 will get implemented something like inteligence to the strength/tough/agile attributes, but this would be the perfect thing on how fast people learn from skill books, or write books (like its kinda odd that the bookkeeper sitting 6 months in his office is the most agile dwarf for years), and more inteligent dwarfs get more happines from good novels but less from lesser ones (common books for common people you know). so this would be a new measurement for dwarfs too!
