If you created the content yourself, enter
If someone else created the content, or if it is based on someone else's work, the source should be the address to the web page where you found it, the name and ISBN of the book you scanned it from, or similar. You should also name the author, provide verifiable information to show that the content is in the public domain or has been published under a free license by its author, and add an appropriate template identifying the public domain or licensing status, if you have not already done so.
Unsure why this image was tagged not sourced properly. It is a government website image and is public domain. The NASA website stated credit for image should be listed as Credit:NASA/JPL-Caltech/ASA/MSSS/UA which I included. Please advise what the issue is? Sara8s001 (talk) 01:29, 26 November 2013 (UTC)
- Hi Sara, thanks for your response to my message. Could you please provide the URL to the image (or, if you got it from offline, the name of the publication)? Commons has a policy that all images should have a complete source in order for everyone else to be able to verify the copyright status (among other reasons). In this case, I can say that images found on NASA's website sometimes aren't actually free (e.g., images they use with permission from the author). Once you have provided the full URL, by all means remove the unsourced tag.
