  Lumen makes significant investments to ensure our digital courseware is accessible, allowing students to learn using superior interactivity, multimedia, and a variety of accommodations for individuals with varying abilities.

  PDFs offer an inferior learning experience compared to the richness and interactivity in our digital courseware. A PDF version of the textbook is available as a print alternative. The PDF does not include interactive content such as simulations, videos, and quizzes and is not vetted for accessibility. For these reasons, we do not recommend using the textbook in the PDF form. The offline version should be used as a print backup rather than as the primary textbook.

  You can download the PDF using the following link:
