Core libraries are included with the Processing software. To add one to a project, select its name from the "Import Library..." option in the Sketch menu. These libraries are open source; the code is distributed with Processing.

Contributed libraries are developed, documented, and maintained by members of the Processing community. Each must be downloaded separately and added to the "libraries" folder inside the Processing application folder. Further directions are included with each library. For feedback and support, please post to the Discourse. We strongly encourage all libraries to be open source, but not all of them are. Information about creating a library is here.
A complete list of libraries can be found online.
