Wikipedia:Manual of Style/Wikipedia books

This page is currently inactive and is retained for historical reference.
Either the page is no longer relevant or consensus on its purpose has become unclear. To revive discussion, seek broader input via a forum such as the village pump.

Note: This guideline only covers books in the Book namespace (Book:Title). Those found on user pages (User:USERNAME/Books/Title) can be written according to whatever style the user chooses.

Scope and structure

Scope

Each book should have a specific and well-defined scope. A reader should not have to guess what the book is about, or be surprised by its content. Use the title and subtitle to define the general scope of the book, and divide the book into topical chapters as needed.

Structure

Not all books need chapters. Books such as Book:Invincible class battlecruisers are short enough to be read without having a chapter structure as a guide. However longer books, such as Book:Canada, will almost always benefit from a solid chapter structure. It usually is a good idea to place general topics first, and specialist topics last. Alphabetical or chronological ordering can also be useful. Use whatever makes the most sense for the needs of the book.

Naming

Books should follow the same naming guidelines as articles do. In particular

The title should be descriptive, rather than try to "grab attention"

YJohn Wayne
NHollywood's most lethal cowboy

Use sentence case, not title case

YCanadian prime ministers
NCanadian Prime Ministers

Note: WP:MOS also applies to Wikipedia-Books, including WP:DASH.

Layout and formatting

All books follow the same basic layout:

==Title==

===Subtitle===

;Chapter 1
:[[Article 1]]
:[[Article 2]]

;Chapter 2
:[[Article 3]]
:[[Article 4]]

...

Titles need to be written as level 2 headers (==Title==). Titles are mandatory.
Subtitles need to be written as level 3 headers (===Subtitle===). Subtitles are optional.
Chapters need to be written with a preceding semicolon (;Chapter). Chapters are optional.
Articles need to be written with a preceding colon (:[[Article]]).

Articles can be renamed (:[[Original title|New title]]) to anything that makes sense for the book. For example, Antarctic Impulse Transient Antenna could be renamed to its common abbreviation ANITA.
Parentheses should be removed from article titles when possible. For example, Duality (mathematics) should be renamed to Duality unless confusion is likely to happen.
For technical reasons, :''[[Article]]'' is not a valid way to italicize articles; instead use :[[Article|''Article'']].

All of these should be written as they usually would be in articles. Meaning that if something would normally be italicized, also italicize it in the book. If it would normally use sentence case, use sentence case in the book. Etc.

Note: Until bug 704 is resolved, the markup used to italicize, bold, or otherwise format article, chapters, etc. will be treated as regular characters. That is ;''Chapter'' will display as ''Chapter'' rather than Chapter.

{{Saved book}} template

This template should always be present at the beginning of books.

{{saved book
 |title=
 |subtitle=
 |cover-image=
 |cover-color=
}}

The title and subtitle parameters should match the title and subtitle of the book (level 2 and 3 headers, respectively). These are not used by the renderer; they are only meant to be used in the preview of the book's cover. Therefore, if the title or the subtitle are too long to fit in, feel free to trim them with ellipses, or to ignore the subtitle.

An image should be chosen for the cover of the book, and the color is customizable. See {{saved book}} for details.

Note: Fair use cannot be claimed on covers, so please choose one which has a compatible license.

Policies

All Wikipedia policies apply to Wikipedia-Books as well as articles. For example, a book that violates neutrality policies can be deleted just like any other page on Wikipedia. Books should also reflect consensus.
