This template is meant to be used at the top of a work,^{[notes ೧]} and its subsections. Fill in any relevant information, and leave unknown or inapplicable parameters empty. Don't remove unused parameters, as this will break the template and make bot maintenance difficult. For easy use, see also the header preloading script gadget in your preferences.

Documentation

Parameters

Standard

title = title of the work, for subpage use relative links (mandatory)
author = name of author (automatically wikilinks)
- where control of linking is required use override_author, and leave the field empty
section = name of subdivision of work, usually used on subpages, typically text without additional formatting
previous = name of previous part of work; relative links on subpages, full links otherwise
next = name of next part of work, relative links on subpages, full links otherwise
notes = notes to explain the work, to add context, or to impart concise information that adds value to the reader; for example, use of {{illustrator}}

The only mandatory field for text is title.

The other standard parameters can be left empty, as required, though please do not remove them as that will cause a template error.

Optional

override_author, while they are automatic with the author parameter. Common uses include links to the Portal: namespace (e.g. for organizational authorship) and the inclusion of multiple authors. See No link to author page. When using this, please leave the author field empty.
editor = editor of the work, not wikilinked Use override_editor for full control. Typically only used on root page, not every subpage.
translator = name of translator, not wikilinked; or override_translator see Translations
contributor = name of the author of this section, if not the same as author the overall work; or synonym section_author.
Not wikilinked; use override_contributor or override_section_author if you need to specify the link target.

If using this "override" option, please do not also include the simpler form of the parameter
section_translator = name of the translator of this section, if not the same as translator the overall work.
Not wikilinked; use override_section_translator if you need to specify the link target.

If using this "override" option, please do not also include the simpler form of the parameter
year = year of publication, adds work to the category for the year, see Category:Works by year.
Enter "?" for a work with no known publication year, and leave blank if you simply don't have this information.

Do not use AD or CE for any Anno Domini/Current Era works (year 1 to the present). Use BCE (do not use BC) for all years before year 1; leave a space between the number and the letters (e.g. 150 BCE).
Approximate dates can be entered in one of the following ways:
1. Decades, centuries or periods can be used instead of a year (e.g. 1060s, 11th century or Medieval).
2. To use a year in the circa format, enter it as "c/Y" (e.g. c/1066 or c/150 BCE). (The use of "ca" or "circa" instead of "c" will also be recognised.) This will display as, for example, "c. 1066".
3. To use a approximate choice of two years, enter it as "Y/Y" (e.g. 1066/1067). This will display as it is written.
The behaviour of this parameter can be further modified by:
- noyear = will prevent the year being displayed in the header but will still add the work to the category for the year. For use in cases where the year is already included in the title of the work. Any use of this parameter, even without text, will work. Example: | noyear = yes. All pages with this parameter will be added to Category:Pages with noyear for tracking its usage.
- noyearcat = will display the year but in the header but will not add the work to the category for the year. For use in cases where a specific subcategory exists for the type of work to avoid flooding the main category for the year. As above, any use of the parameter will trigger this action. Pages will be added to the tracking category Category:Pages with noyearcat.
- override_year = will display the given text and will not attempt to add the work to the category for the year. For use in any other case not covered by the other parameters. Pages will be added to the tracking category Category:Pages with override year.
edition = yes to refer to further information on the work's talk page.
shortcut = The shortcut to this page, if it exists. This is normally reserved for very large reference works (e.g. EB11)
cover = The image used as a cover for the book when exported. Do not include the "File:" prefix, e.g. Foobar.jpg. You can use a page of a multi-page file using Foobar.djvu/7.

portal
related_author

Sister wiki links are now typically now provided through Wikidata linking which manages link rot issues. So while the parameters are shown here for fullness of scope, such usage would be used to override automated linking rather than as a primary use.

Relative links

With lengthy, multi-page works, using relative links is highly recommended. This shortens the code and ensures that a work remains linked together even if it is moved or reorganised. The three formats are [[/subpage]] (subpage), [[../]] (parent), and [[../sibling]] (sibling)^[೧]; see the example usage below. Note that [[../]] will expand to the title of the parent page, which is ideal if the work is renamed at a later time.

This depends on a page conforming to the page title standards in the Style guide, with works in the form [[Work title]] and [[Work title/Subpage]].

↑ The specific form [[../sibling/]] can be used on a sibling to provide both a relative link, and the link label to a sibling page.

Chapter titles

In general, include chapter titles in the "section" field, but avoid including them in the "previous" and "next" fields. For example: Lua error in ಮಾಡ್ಯೂಲ್:Header/year at line 430: bad argument #2 to 'inNamespaces' (unrecognized namespace number '114').

Special cases

Translations

 |translator=Joe

The name of the translator. This will automatically be linked to an author page unless it contains the "[" character.

A value of "?" or "unknown" adds {{No translator info}} to the page.
A value of "not mentioned" adds translator not mentioned to the page. This should only be used where the translated work was published before 1929.

No link to author page

| author= |override_author=Joe

Displays the author's name without a link to an author page (for works that don't have traditional authors).

Usage examples

Normal

{{header
 | title    = [[../]]
 | author   = Lewis Carroll
 | section  = Chapter 3: A Caucus-Race and a Long Tale
 | previous = [[../Chapter 2|Chapter 2]]
 | next     = [[../Chapter 4|Chapter 4]]
 | notes    =
}}

Sister, related author, and portal wiki links

You can link to Wikisource portals and other WMF projects using the optional wiki links parameters where required to override the data provided from Wikidata. These are:

portal, related_author
wikipedia, wikispecies, commons, commonscat, wikiquote are typically applied from Wikidata data through interwiki links, or through linking of ಮುಖ್ಯ ವಿಷಯ (P921) so should only be used to override the default
wikinews, wiktionary, wikibooks, wikiversity, meta

For portal this would generally be added to the root page of a work, rather than added repeatedly for each subpage. Usage on a subpage would be useful where the subpage alone has a relationship with the specified portal, whereas the parent work does not have that relationship.

These links are generated using {{plain sister}}

{{header
 | title    = Kinematics of Machinery
 | author   = Franz Reuleaux
 | section  =
 | previous =
 | next     =
 | notes    =
 | portal  = Technology/Germany
 | wikipedia = Kinematics of Machinery
 | related_author = Albert Einstein
}}

Shortcuts

If a work has a shortcut, you can add it using the shortcut field. This should be in accordance with the shortcut guidelines, and shortcuts should not be used for every work.

{{header
 | title    = 1911 Encyclopædia Britannica
 | author   = 
 | section  =
 | previous =
 | next     =
 | notes    =
 | shortcut = [[EB1911]]
}}

Lua error in ಮಾಡ್ಯೂಲ್:Header/year at line 430: bad argument #2 to 'inNamespaces' (unrecognized namespace number '114').

Advanced manipulation

Alternative headers

↑ Certain projects have customised versions of {{header}} that are used to present these works, eg. {{DNB00}} is used for the project involved with Dictionary of National Biography. For these works it is permissible and recommended that these variations are used. New alternatives to {{header}} should be discussed on the talk page, and consequentially listed on each project's pages.

JavaScript extraction

The header values can be extracted using JavaScript by accessing the text values of their span wrappers:

value	wrapper id
title	header_title_text
author	header_author_text
translator	header_translator_text
previous	headerprevious
next	headernext
notes	none

Microformat

The HTML markup produced by this template includes an hCard microformat, which makes the person's details parsable by computers, either acting automatically to catalogue articles across Wikipedia or via a browser tool operated by a reader, to (for example) add the subject to an address book or database. For more information about the use of microformats on Wikimedia projects, please see Wikipedia's microformat project.

Sub-templates

To include a URL, use {{URL}}.

Please do not remove instances of these sub-templates.

Classes

hCard uses HTML classes including:

adr
agent
bday
birthplace
category
country-name
deathdate
deathplace
extended-address
family-name
fn (required)
given-name
honorific-prefix
honorific-suffix
label
locality
n
nickname
note
org
role
url
vcard

Please do not rename or remove these classes; nor collapse nested elements which use them.

Technical

This template delegates some logic to Lua modules and uses sub templates to divide up the structural code:

Module:Header the main logic for parameter handling
{{header/main block}} the "main cell" and previous/next links
{{header/notes block}}

Most CSS is inline, with some provided by MediaWiki:Gadget-Site.css and MediaWiki:Gadget-SiteHeader.css. This is deliberately not TemplateStyles to avoid polluting exports with the (non-exported) header styling (and also because the layout exemption logic is currently incompatible with TemplateStyles).

Tracking categories

This template currently uses the following categories to track maintenance tasks, errors, and feature usage.
