<div style="text-align: center; font-size: x-large; padding: 1em;">ENCYCLOPEDIA OF MATHEMATICS MAKES NO GUARANTEE OF VALIDITY</div>

The Encyclopedia of Mathematics is an online open-content collaborative encyclopedia, that is, a voluntary association of individuals and groups working to develop a common resource of mathematical knowledge. The structure of the project allows anyone with an Internet connection to alter its content.  Although members of the Encyclopedia's editorial board will be periodically reviewing the content for completeness and accuracy, please be advised that not all of the information contained with the Encyclopedia has necessarily been reviewed by people with the expertise required to provide you with complete, accurate or reliable information.

That is not to say that you will not find valuable and accurate information in The Encyclopedia of Mathematics; much of the time you will.  However, '''We cannot guarantee the validity of the information found here.'''  The content of any given article may recently have been changed, vandalized or altered by someone whose opinion does not correspond with the state of knowledge in the relevant fields.  Note that most other encyclopedias and reference works also have [[Wikipedia:Non-Wikipedia disclaimers|similar disclaimers]].

=== No formal peer review ===
We are working on ways to select and highlight reliable versions of articles.  Our active community of editors uses tools such as the [[Special:Recentchanges]] and [[Special:Newpages]] feeds to monitor new and changing content.  However, The Encyclopedia of Mathematics is not uniformly peer reviewed; while readers may correct errors or engage in casual [[Wikipedia:Peer review|peer review]], they have no legal duty to do so and thus all information read here is without any implied warranty of fitness for any purpose or use whatsoever.  Even articles that have been vetted by informal peer review or [[Wikipedia:Featured articles|''featured article'']] processes may later have been edited inappropriately, just before you view them.

'''None of the contributors, sponsors, administrators, or anyone else connected with Wikipedia in any way whatsoever can be responsible for the appearance of any inaccurate or libelous information or for your use of the information contained in or linked from these web pages.'''
