Can I modify some clipart and resubmit it to the Open Clip Art Library?
Yes, since the clipart is Public Domain you’re welcome and encouraged to modify and resubmit it, however we do ask that you observe a few guidelines. First, if the changes are minor such as fixes or slight tweaks, please submit these back to the original author if possible, so we can avoid having several near-duplicates of a given image. Second, please try to notify the original artist of your changes to provide them the courtesy of knowing how their work will be reused within the project. Finally, in your README, please include a mention of the original artist’s name and the identity of the original image.
