Also, you can incorporate multimedia elements that are licensed for your use through the Creative Commons, as long as you provide proper attribution. The Creative Commons search feature is great at helping you find music, videos and images licensed through the Creative Commons.
Creative Commons licenses were designed for people like you, but it’s important to understanding the differences between the six licenses offered through Creative Commons.
Whenever you use material that is not your original creation, it is important to attribute the source properly. If your style guide does not already dictate the proper attribution format, I recommend adding a statement that identifies the non-original work and includes a hyperlink to the location where you found the media file. For example:
“Put the Needle Down” by Admiral Bob. Licensed under Creative Commons.
