The Open Clip Art Library contains over 6000 new and 7000 archived pieces of clip art for your delight and delectation. It’s a pipeline source for Open Source products like Inkscape and OpenOffice so it needs support of course so spread the word. Great idea, nicely done.
This project aims to create an archive of user contributed clip art that can be freely used. All graphics submitted to the project should be placed into the Public Domain according to the statement by the Creative Commons. If you’d like to help out, please join the mailing list, and review the archives.
