How to Adapt an Open Textbook

Attribution Statements

All Creative Commons licenses contain an attribution (BY) clause. This means that you must include a statement that gives credit to, or attributes, the creator of the work from which you have borrowed, whether it’s text, an image, a video, or other item. If you have made a change, indicate that in your attribution statement.

As far as how and where to place attribution statements for text or media taken from another source or sources, best practices state that you should place them at the bottom of each affected web page. Clearly mark all of these with a heading called: “Attributions”. Several attribution statements can be listed under this heading. Here are examples.

Example of an attribution statement for adapted text

This chapter is an adaptation of Natural Disasters and Human Impacts (on Open Geography Education) by R. Adam Dastrup and Maura Hahnenberger, and is used under a CC-BY-SA 4.0 International license.

Note:

  • The statement is clear, simple, and contains all elements required for a complete attribution: title of the work used, author(s), and license type. A link is provided to the original work, the home page of the website (this is optional), and the license type.
  • There is no need to name the adapting author in this statement. This information should either be included on the Book Info page as a main author OR if you want to indicate which author wrote/adapted which chapter, you can use the Chapter Author option at the bottom of each chapter/web page in Pressbooks.
  • If the book is to be CC-BY licensed, then you will need to address the conditions dictated by the license for each resource you are using in your adaptation.  At the bottom of the Chapter page in Pressbooks, there is an option to set the license type for that page which will override, for this page only, the overarching license chosen for the book on the Book Info page.
  • If the chapter contains some original material AND some material from another source, then rather than saying “This chapter is an adaptation of….”, say “This chapter contains material taken from….”.

Example of an attribution statement for an adapted image

Figure 1.2
Dog by David Locke is used under a CC-BY 2.0 license. Modifications to this photo include cropping.

Note:

  • The statement is clear, simple and contains all elements required for a complete attribution: title of the image, photographer, and license type, as well as a note of the changes made. A link is provided to the original work, the home page of the photographer (if available), and the license type.
