The project namespace or Wikipedia namespace is a

administration pages with information or discussion about Wikipedia. Pages in this namespace will always have the prefix Wikipedia:. They can also be reached by alias WP: or the standard (for any MediaWiki
site) prefix Project:. Its namespace number is four (4).



Pages within the "Project namespace" themselves are not part of the

style conventions as articles. Nevertheless, these pages, as with all pages, should be accessible and must comply with Wikipedia's conduct and legal

for more information.

Pages within project namespace

The project namespace pages are organized according to their function within the overall project schema. This includes Wikipedia official policies and guidelines, process pages, discussion pages, optional essays, maintenance pages, informative pages, and historical pages.

For lists of pages in the project namespace, see:

A main gateway for the project namespace is Community portal. The Community Portal includes categorized links to the more commonly used pages related to the project. A link to the Community Portal page is available in the sidebar.

Policies and guidelines pages

Wikipedia review process. These pages are marked with the {{policy}}, {{guideline}} or {{MoS guideline}} template. For summaries of key policies, see List of policies. For summaries of key guidelines, see List of guidelines. For summaries of guidelines about Wikipedia's house style, see the Manual of Style contents page. For information on editing policies or guidelines see Edits to policies and guidelines

Process pages

Process pages help facilitate application of the policies and guidelines governing all Wikipedia pages (e.g., Wikipedia:Articles for deletion). See Wikipedia processes for details.

Information and discussions

Many pages in the Wikipedia namespace have nothing to do with rules or implementation of those rules, and thus do not belong in the above categories. See Wikipedia:The difference between policies, guidelines and essays for more information.

Discussion and noticeboard pages

Some pages are designed for discussions, such as the

requests for comments pages. While many of these pages operate like talk pages, some of them have posting rules (at the top of the page) which may be administratively enforced, and they also have their own talk pages, usually about the management of the noticeboard or other process in question. To ask a question or make a request, see the request directory. For a listing of ongoing discussions and current requests, see the dashboard

Maintenance pages

Maintenance pages are used to help facilitate the organization and

Wikipedia:Dusty articles). The Special namespace also contains bot generated maintenance reports (e.g. Special:UncategorizedPages). See Wikipedia maintenance
for details.

How-to and information pages

Informative and instructional pages are typically edited by the community; while

vetting. These pages are typically marked with the {{Information page}}, {{Wikipedia how-to}}, or {{Supplement}}[a]

There is a large amount of overlap between the Help namespace (which provides mainly technical information) and the Wikipedia namespace (which provides mainly procedural information and interpretation). For this reason, redirects and hatnotes are often set up between these two namespaces. See Help:About help pages for more information. For a listing of how-to and information pages, see the help directory.

Essay pages

Essays about Wikipedia may be written by anyone; some represent widespread norms, others only represent minority viewpoints. Essays can be long

one of the various {{essay}} templates. See Wikipedia:Essays for more information. For a listing of essays, see the essay directory

WikiProject pages

Pages of a

These pages are typically marked with the {{WikiProject status}} or {{WikiProject advice}} template. For a listing of projects, see the directory of WikiProjects. For additional resources, or if you have any questions, please visit the WikiProject Council

Historical pages

A historical page or process is one which is no longer in use, or is no longer relevant or consensus has changed about its content. They are kept as records of past Wikipedia processes to give context to historical discussions and to inform future discussions on similar topics. These pages are typically marked with the {{

Creating new project pages

Essays and information pages may be established by writing them and adding {{

WP:PROPOSAL for procedural details). For general recommendations about the creation and improvement of existing guideline and policy pages, see Wikipedia:Policy writing is hard

The project namespace contains many pages and a lot of information. Try to avoid creating new pages unnecessarily. Before creating a new page, you should consider looking through the

WikiProject at the proposal page, if there are enough willing editors to participate in the project. Already existing WikiProjects can be found in the directory of WikiProjects

Deletion of project pages

If editing can improve the page, this should be done rather than deleting the page. Disputes over page content are usually not dealt with by deleting the page, except in severe cases. The content issues should be discussed at the relevant talk page, and other methods of

appropriate template

The usual deletion process is to post a request at

miscellany for deletion to have project pages deleted
. Make sure that a notice of the request is posted to the talk page of the affected project. If the project is under a parent WikiProject, a notice should be posted there as well.

Essays, information pages, and other informal pages that are only supported by a small minority of the community may be moved to the primary author's userspace over deletion. The Wikipedia community has historically tolerated a wide range of Wikipedia related subjects and viewpoints on user pages.

It is generally preferable that

Copyright violations

If the entire project page is a copyright violation, nominate it for

Namespace history

The Wikipedia namespace began after the January 2002 release of the Phase II software. Prior to that, an index of related pages was maintained at Wikipedia utilities, which remained for some time afterwards at Wikipedia:Utilities. This list of pages in the project namespace has been replaced by the pages as described above.

Project namespace search

By default, Wikipedia's search engine looks in the Article namespace. To search in the Wikipedia namespace, you would type the project page prefix Wikipedia: (Wikipedia followed by a colon) or WP: (WP followed by a colon), followed by some text identifying or relating to the search target. You can also use the Special:Search box below to locate Wikipedia/Project namespace pages. See Help:Searching for more information.

  1. ^ The {{Supplement}} template used for "explanatory essays" is intended as a separate "supplement" banner used for pages derived from policy improvement conversations. The template does not indicate a "higher status" within the community for an essay, but is used to denote that the essay in question has wide acceptance to be linked from said policy or guideline page. See Template:Supplement for more information.
