[[File:book_sprite_preview.png|132px|right]]A '''book''' is an item that can be written on, storing historical events, [[knowledge]], and art. Books use [[sheet]]s made from [[plant fiber]] (paper), [[parchment]], or papyrus. They are created by [[historical figure]]s in [[world generation]], [[adventurer mode|adventurer]]s, and by [[scholar]]s and visitors in [[fortress mode]], or can be copied by [[scribe]]s. Travelers and [[trading|traders]] carry books to different sites and [[library|libraries]], spreading information as a result. There are two forms of books: '''codices''' {{Tile|◘|7:1}} (sing. ''codex'') and '''scrolls''' {{Tile|∞|7:1}}. Both forms have different methods of creation, but they are identical in function. Codices are known as '''quires''' {{Tile|≡|7:1}} prior to being bound. Written books are treated as [[artifact]]s, with the exception of copies. Original written works are recorded in [[legends mode]] and appear in the {{menu icon|o}} Artifacts screen in fortress mode. Books are titled based on their subject matter, with copies identified by "(copy)" at the end of their title.

Quires and scrolls are found under "tools" in the {{k|k}} Stocks screen, and codices can be found under "codices". Written and unwritten books are stored in [[stockpile]]s with Finished Goods enabled. Original written works can be separated from copied and unwritten books in stockpiles by toggling the stockpile's settings to accept only artifact-level [[core quality|core or total quality]] items. Rollers and bookbindings can be separated from scrolls and books in stockpiles by toggling the stockpile's settings to accept only the corresponding materials: when a scroll/book is created, its core material is the material of the former sheet/quire, while the rollers/bookbinding becomes a decoration and is ignored for material checks.

If a [[library]] with available book-space is present, written books will instead be stored in [[bookcase]]s, and unwritten books in [[container]]s.

== Physical Forms ==

=== Scroll ===

Scrolls are made from [[sheet]]s and [[scroll rollers]]. Scrolls can be written on and stored right after being made.

=== Quire and codex ===

Unlike scrolls, codices require a two-step process to be made. The initial form of a codex is known as a quire. Quires can be written on, read, and used as copies, similar to scrolls. Once written on, quires can be combined with a [[book binding]] and [[thread]] to create a codex.

Binding a quire into a codex should increase the overall [[value]], however, the transformation currently discards some of the quire's properties (text length, material value, etc.).{{bug|9409}} This makes codices a terrible way to generate wealth, since they tend to actually be worth much less than the combined value of the constituent parts. If trying to increase [[wealth]], it is recommended to leave your scholars' works in quire form.

== Production ==

:''See also: [[Paper industry]]''

Quires are made from [[sheet]]s at a [[craftsdwarf's workshop]] by a dwarf with the [[bookbinding]] labor. Only a single sheet is needed per quire. Codices are then created from one thread, one book binding, and a written-on quire at a craftsdwarf's workshop by a bookbinder (perhaps even the original quire crafter).

A scroll is made from a single sheet and a scroll roller at a craftsdwarf's workshop by a bookbinder. Both book bindings and scroll rollers can be made out of wood, stone, metal, or glass. Components made of wood and stone are produced at a craftsdwarf's workshop, metal at a [[metalsmith's forge]], and glass at a [[glass furnace]].

[[Decoration]]s such as gems and ivory can be added on unwritten scrolls. Codices cannot be normally decorated, with the exception of untitled codices. Book bindings or scroll rollers cannot be decorated.

==== Missions ====
It's also possible to raid another culture, hoping to steal their books for yourself. When using the Raid menu, any books, codices and scrolls currently in possession of the target culture are listed along with any [[artifact]]s, and so can be specifically selected. See the [[Mission]] article for more information.

== Usage ==

=== Reading ===

Written books can be read. Readers will gain information on the subject they read about in a book. Contents of a book cannot impact specific [[ethics]], although personal values are a different matter, and one [[Necromancy| particular subject]] can have profound ''physical'' effects on the reader. Reading a book will satisfy the reader's [[need]] to self-examine and think abstractly.

Adventurers can read books in their possession by pressing {{k|I}} then selecting them from their inventory. Characters must possess a [[reader]] skill of at least novice level in order to read a book. This skill can only be leveled up in-game by reading books, which is impossible to do without any reader skill to begin with. Raising the reader skill in advance during character creation (or simply adding some amount of NATURAL_SKILL to one's chosen race in the raws) is therefore crucial.

Fortress citizens and visitors will read available books in a library at their leisure. [[Bookkeeper]]s do not require a book to update stockpile records, oddly enough.

=== Writing ===

Unwritten quires and scrolls stocked in a library as writing material will be used periodically by scholars and scribes to write original works and copy existing works, respectively.

Adventurers can write their own books:  First, have an unwritten scroll or quire wielded in hand, or on the tile where you stand. Press {{k|x}}, select {{k|w}}rite, and choose the object you want to write on. You will be given a list of memorized content and prose to write about, which includes guides, essays, manuals, chronicles, letters, short stories, novels, plays, poems, choreographs, and musical compositions. For prose options, a random known subject will be used. Writing a book will take up several in-game hours. If you are interrupted by enemies, writing will stop and the writing material will be unused.

=== Combat ===

Although hardly ideal for the purpose, creatures carrying books have been known to use them in combat, with varying results. The combat effectiveness of the written word is determined in large part by the materials used in the book or scroll's construction. Books are blunt weapons, so heavy metal books will be dramatically more effective than light wooden ones. Fighting with a book trains the [[Macedwarf]] skill.

== Subjects == 

=== Art ===

Art books describe poems, choreographs, and musical compositions. Art books are titled after their art piece's name. In [[adventure mode]], reading a book about an art form is one of the few ways to learn it. Presumably dwarves reading art books will be able to perform what they've read at a [[tavern]] as well.

=== Knowledge ===

[[Knowledge]] books, referred to as ''manuals'', include [[topic]]s on mathematics, philosophy, history, geography, medical science, natural science, astronomy, engineering, and chemistry.

Civilizations practice different forms of scholarship. Dwarves practice all forms of scholarship (while still preferring craftsdwarfship to the art of writing books), elves do elven stuff, and for humans, it is randomized for each instance of their civilization (scholar types are based on the civilization's values and jobs).

=== Secrets ===

Books containing "secrets of life and death" are occasionally written during world generation by [[necromancer]]s and various [[demon]]ic rulers. Any mortal creature who reads one will immediately learn the secrets to [[immortality]] and the ability to raise the [[undead|dead]]. Necromancy books can be found in a necromancer's [[tower (necromancy)|tower]] among other types of books, including the original [[slab]] which the secrets originated from. A book will state it "concerns the secrets of life and death" if it does, note that books with descriptions like "Concerns the learning of the secrets of life and death" do ''not'' contain the secret, and as such cannot train necromancers.

Necromancers [[siege|invading]] the fortress may bring their books along, which could be necromancy books. Looting a necromancy book and storing it in a library will cause all of the fortress population to gradually become immortal masters of death every time one of them reads the book, and this process can be accelerated by creating copies of the book. Adventurers who have learned the secrets of life and death have a chance to create a new necromancy book when writing a manual.

=== Other ===

Books may be autobiographies, or about other historical characters or locations the author has had contact with. Presumably the relevant "Form" topics must have been discovered by an individual's civilization for biographies, autobiographies, etc. to be written. [[Topic#History|Autobiographical adventure]], for example, unlocks autobiographies. Most forms are part of the [[Topic#history|history]] branch, but creation of [[Topic#Geography|atlases]], [[Topic#Philosophy|dictionaries]] and [[Topic#Astronomy|star charts]] require other disciplines.  Books may also be commentaries on other books.

== Literary Forms ==
The content of a book is written in one of many literary forms. The literary form decides the purpose of the text, with different literary forms allowing for certain subjects. Some literary forms need to be "unlocked" by scholars discovering a certain [[topic]], and cannot be written before such a discovery.

In terms of availability of literary forms in fortress mode, manuals are most commonly written by scholars as the culmination of research - other forms may be written by scholars or any other figure, but this is a rare event. Adventurers are the most reliable way to get non-manual books inside your fortress. The second best way is to simply trade for them from caravans.

All forms have been found, but currently the precise mechanics behind learning knowledge or receiving a change in values from them is still unclear.

{| class="wikitable"
|-
! Literary form name !! Purpose !! How to unlock
|-
| Manual || Writes down a randomly-selected form of knowledge the adventurer is aware of, to be learned by future readers. Most commonly this will be musical, poetic, and dance forms the adventurer knows or composed, including also scientific research the adventurer has learned - necromancer adventurers can spread the secrets of life and death by writing manuals about them. || Does not require unlocking.
|-
| Guide || General writing about a specific site, generally described as "concerning" that town, dark pit, etc. without going into detail. || Does not require unlocking.
|-
| Chronicle || In-depth writing about a particular site, group, or civilization; presented as multiple chapters, each chapter relating to a historical event related to the writing's subject. It teaches histfigs about the group. || Does not require unlocking.

Right now, adventurers can only learn new art forms and academic knowledge from books. If an adventurer reads a book of a given literary genre that requires an academic topic to unlock, this will teach the academic topic, so if an adventurer without academic knowledge reads an autobiography, they'll learn the autobiography topic. For some of the advanced forms, such as Genealogy and the Treatise on Technological Advancement, adventurers may sometimes end up writing an essay. This was asked about in the forum's Future of the Fortress, and the reply indicated this was because books are slightly half-implemented <sup>[http://www.bay12forums.com/smf/index.php?topic=169696.msg8071983#msg8071983 1]</sup>.

== Titles ==

Books are named from the two text files found in \data\vanilla\vanilla_text\objects. Those files are 'text_book_art.txt' and '[[text_book_instruction.txt]]'
text_book_art.txt will be used when a poem or song is created both in worldgen and by adventurers.
text_book_instruction.txt will be used when a book is written both in worldgen and by adventurers/fort scholars.
Note: book_art.txt is also fair game for book titles, because it is always possible to just name a book after a poem/song, as long as the content is (a transcription of) that song or poem.

These files are called upon book creation - so you can modify the files in an existing save, altering the names of all future books - it would be possible to directly name your book in adventure mode this way.

There are 7 tokens which can be used in book titling. Poem/song names are '''always''' available to be book titles, even if your book_instruction.txt only contains the instruction, "[ANY_PRONOUN]". 

It is possible to get a poem with no name at all - which could be a vanilla bug, or the game will accept a misplaced space as a title. {{verify}}

You only get one roll per name per title. So "[NAME] Is Not [NAME]" will say something like "The Tower Is Not The Tower".
[NAME] and [NO_ART_NAME] are not handled separately in this case. '[NO_ART_NAME] Inside [NAME]' will result in "Tower Inside The Tower"
Rarely, this won't happen. All other tokens are rolled each instance, so [ADJ] [ADJ] [ADJ] [NOUN] will result in some nonsense like "Good Hungry Flaxen Obsession". Works for all of them, but keep in mind that it is a random roll, so several [ANY_PRONOUN]s is almost certain to have some repeats. 

These are the 7 tokens for these two txt files:
[NAME]
Examples: The Tower, The Tree, Bronzemurdered, Likot Ubendeb, Animal Behaviours

Notably, these may or may not be plural and/or have an article.
Name is directly related to the content of the book.

[NO_ART_NAME] (no article name)
Examples: Tower, Tree, Bronzemurdered, Likot Ubendeb, Animal Behaviours

Notice that the inserted text may still be plural - limiting its usage.
These likewise are related to the content of the book.

[NOUN]
Examples: Despair, Roots, Scrolls, Wheel-and-axles

Again, may or may not be plural. These seem to have very little correlation to the book's topic. If it has any relationship to the content of the book, it could be words within the author's entity's vocabulary.

[ADJ]
Examples: Boyish, Inky, Angry, Bronzed

Also seem to have little correlation to the book's topic. They are currently guessed to be from the civ, if not purely random.

[ANY_AGE]
Examples: The Age Of Legends, The Age Of Hill Titan and Dragon

Will only pull ages from the world's history, not from all possibilities.

[ANY_PRONOUN]
Examples: He, She, We, They

It is believed it only generates subject pronouns (not "Us" or "Them"). Past tense makes this easy to use.

[PHRASE]
Examples: The Fool Laughs, The Day Can Say It In The End, It Foretells Afterwards, The Day Mourns

Due to the wide variety, this is pretty hard to use. 

-=-=-=-=-=-=-

So, you can let the game do a lot of the work for you and generate more of this style:
The [ADJ] [NO_ART_NAME]
[NAME], [ADJ] [NOUN]
[PHRASE], [ADJ] [NO_ART_NAME]

Or you can be as specific as you'd like:

My Mother Always Said, [PHRASE].

[NAME], And Its Utmost Importance.

[NO_ART_NAME], Do You Love Me?

I Once Saw [ADJ] [NOUN], And So I Said, [PHRASE].

Poetic forms are generated in the same manner as Taverns/Locations.

== Bugs ==

* Binding a quire into a codex destroys the material definition and value.{{bug|9409}} This loss of information also results in the book being a single page long. Written works can be left in their quire form to retain their properties.
* Quires targeted by any active jobs (e.g. being read) are unavailable for binding.{{bug|9269}}
* Scrolls made by the player always have two sets of rollers, one set supplied during construction and the other set randomly generated from nothing by the DEFAULT_IMPROVEMENT tag working in the wrong place.{{bug|9249}}
* In adventure mode, placing and removing books from a bookcase can duplicate them, resulting in "phantom" books.{{bug|10245}}
* Codices will sometimes appear without a title. These codices are not considered as artifacts; they do not appear in the Artifacts list menu and are not stored in artifact-specified stockpiles. Since all codices must be derived from a written-on quire, all codices (except copies) should in theory be an artifact and possess a title.
* Codex/Codices/Scroll can be stuck on the map, and not be interacted with (from raid or visitor), which can be fixed with [[DFHack]].{{bug|10288}}
