Determining if a Resource is OER, Creative Commons Licensed, or Public Domain
Look for the Creative Commons button somewhere on the page,
Look for a link to the creativecommons.org website in the page's source code (in Firefox do CTRL-U to show the source code and CTRL-F to bring up the "find" dialog - you're looking for a link that includes the creativecommons.org domain and the phrase 'rel="license"'), or
Look around the website for the copyright or terms of use statement (hopefully this will include Creative Commons or the public domain), or
If worst comes to worst, find contact info for the author and email them to ask about how the content is licensed
Use the Public Domain Calculator to determine if a piece of work is in the Public Domain
