Note: Sources may have individual or group authors. Group authors are often organizations or government agencies. Sometimes it is not 100% apparent that an organization is the author. It may require you to hunt for the author a bit -- look at the bottom of the page and also at other sections of a website, such as the About Us section. Also, the sponsoring organization may sometimes be discovered by looking at the URL.
