About Creative Commons Licenses

If you are looking for content to add to your textbook, you should look for and use Creative Commons licensed material and works in the public domain.

Why You Should Use Openly Licensed Materials

Using copyrighted material creates a barrier to the usage of your open textbook. Creative Commons licensed material, on the other hand, can legally be shared and reused – this is one of the best things about open textbooks!

To use copyrighted material in your textbook, you must first obtain written permission from the copyright holder. You then must clearly note in the textbook which material is under copyright so others using the book know they cannot reuse or modify that material and must either replace it or obtain permission from the copyright holder.

License Types for Open Textbooks

Ideally, resources added to an existing textbook as part of a modification or newly created textbook should use a CC-BY license or CC BY-NC license. Other CC licenses are acceptable except for the CC-BY-ND and CC-BY-NC-ND (no derivatives) licenses as these do not allow the textbook to be revised.

When it comes to working with open textbooks (and open educational resources in general), one of the conceptual hurdles faced by many people is around the notion of adapting or changing someone’s work. What exactly can be adapted within the scope of an open textbook, and won’t the original author get upset if you change their work?

Changing someone’s work can feel uncomfortable. But be assured that if the author of the textbook has released their textbook under a Creative Commons license that allows for adaptation (which is any Creative Commons license that does not have a No Derivative [ND] attribution added to it), they expect that you will change the content, providing that you give them the proper attribution.

What Can You Change?

Anything and everything in an open textbook can be changed as long as the conditions of the open license are met. The modifications or changes you make can be fairly minor or major depending on what you need to do to make the book work for you. That is the beauty and power of open textbooks. You are in charge of the resource. You have been given permission to change it ahead of time by the original author. Take advantage of it!

No Derivative (ND) Attribution licence

If the book you are looking to adapt has an No Derivative (ND) license you still have the option of writing to the original author(s) to ask if you can adapt their work for your teaching. If they say no, you can still use the text (or chapters of the text) in your teaching, but can’t adapt or change the wording of the chapters, or chapter organization of the textbook.

Using Copyright Material in Your Open Textbook

Be careful if you are consulting copyrighted textbooks when writing your new open content. Make sure that your newly created open textbook is not based on, or adapted from an already existing copyrighted work.

Note that charts, tables, figures, etc. used in academic journals are often copyrighted by those journals and should not be used unless the journal is published under an open license.

Open access content can be used and cited under the terms of the CC license of that journal or book.
