This open textbooks has been published openly using a\u00a0<\/span>Creative Commons\u00a0license<\/a>, and is offered in various e-book formats free of charge, or as a printed book available at cost <\/span>from a printing service like the Ryerson University Campus Store or Copyrite.\r\n<\/span><\/div>\r\nInformation about licensing should also be added to the book information section of PressBooks<\/a>.

Licensing an Adaptation<\/h2>\r\nIf you are adapting an existing open textbook, your additions can be released with a CC-BY license, but the rest of the book must be released under the license of the original book. In other words, you need to respect the license of the original work. You can only attach a CC-BY license to the parts of the book you have created.\r\n\r\nHowever, if the textbook you are adapting has a Share-Alike license attached to it, you can only release the book with the same license as the original. The Share-Alike clause means that you must use the exact same license that was used in the original for ANY adaptation.\r\n\r\nThe license should be noted in a few places in the book.\r\n
    \r\n \t
  1. In the preface of the book there should be a statement that makes it clear that the book is a derivative of an original textbook.<\/li>\r\n \t
  2. There should also be a list of what changes were made so readers know exactly what parts are new and what parts are from the original source.<\/span><\/li>\r\n<\/ol>\r\nAs an example, in the preface of the book, you could say:<\/span>\r\n
