 * PlanetMath.org — Mathematics for the people, by the people.

PlanetMath is a virtual community which aims to help make knowledge more accessible. PlanetMath's content is created collaboratively: the main feature is the mathematics  with entries written and reviewed by members. Entries are written in , the of the worldwide mathematical community. Articles are then rendered for presentation on the web using LaTeXML, and links between them are added using NNexus.

PlanetMath originally used the  wiki engine software, which was written especially for PlanetMath. However, some would argue that Noösphere has diverged enough from more traditional wiki that it is no longer a wiki engine. The Noösphere wiki content was originally released under the (GNU FDL, or GFDL), but this was subsequently changed to the  (CC-BY 3.0).

In March 2013, a new version of the PlanetMath wiki was released on the then new developmental  wiki engine. Its content is now released under the (CC-BY-SA 2.0).

As of 2018, source files are editable via PlanetMath's repositories on GitHub: acceptable pull requests will be merged by one of our editors. Along with this change to the way editing works, the legacy forums have been decommissioned, and we have created Gitter discussion channels for each mathematics subject category, in order to facilitate real-time discussion.

The PlanetMath.org website is hosted by the Faculty of Mathematics at the University of Waterloo, Ontario, Canada. PlanetMath.org, Ltd., is a 501(c)3 non-profit, in Alexandria, Virginia, USA.
