Copyright law offers protections for original and fixed works from the moment they are created. Those protections include several exclusive rights that belong only to the copyright owner. Some authors want to allow users to share, adapt, and display their work without needing to ask permission. Using a license provides clear conditions for what kind of uses the author wants to allow and which they do not.

Think about a driver's license. A driver's license indicates that you have permission to legally operate a motor vehicle. If you get caught driving without a license, then your use of the car is illegal. With the license, your use becomes permissible. However, the driver's license isn't all-encompassing. If you want to legally drive an 18-wheeler, you need a special license. Creative Commons licenses work similarly by providing authors several licenses to select from that convey different permissions to the user.

Creative Commons is a well-known, standardized method of communicating which rights an author wants to share with users. They provid six difference licenses that can be easily applied to your work.

The TASL Method was developed by the creators of the Creative Commons licenses as an easy way to provide attribution for Creative Commons licensed materials. This method ensures that all aspects of the license are being properly met.

TASL stands for Title, Author, Source, and License:

• Title - If a title was provided for the material, include it. Sometimes a title is not provided; in that case, you can ignore this part.
• Author - Include the name the author. It is also a best practice to link to the author's profile on the website you are using, if available.
• Source - Provide the source of the material so others can find it. This is usually a URL or hyperlink where the material resides. The hyperlink can be included in the title to make the citation more visually appealing.
• License - Remember that there are six different CC licenses; which one is the material under? Name and provide a link to it, eg. http://creativecommons.org/licenses/by/4.0/ for CC BY.
