Sketchory: 250,000 Drawings Available through Creative Commons Licenses

Sketchory is a growing collection of over 250,000 drawings that may be freely shared, in unlimited number, by keeping to a Creative Commons license. These works come from SketchSwap.com, a site where people from all over the world submit sketches to share. They may be used in publications, for example, providing the conditions of the Creative Commons license are met. This is another example of the copyleft movement, which seeks to provide alternatives to the restrictions of the "all rights reserved" paradigm of copyright law.
