What Are Open Textbooks?

Open textbooks are typically authored by faculty and published on the web with the support of universities or new commercial companies. This new business model enables free online access to textbooks.

Open textbooks are usually governed by Creative Commons licenses that enable users to download, customize or print the textbook without expressed written consent of the author. In contrast, new commercial companies provide free access to the textbook content online, while charging lower prices for print products and supplemental services.

The EDUCAUSE LEARNING INITIATIVE has provided a nice overview of the 7 Things You Should Know About Open Textbook Publishing (pdf) by Judy Baker and Jacky Hood from Foothill College (California Community College)

Course Description:
Allocation of resources and distribution of income as affected by the workings of the price system and by government policies. Notes: May be taken concurrently or prior to Econ 1A. Meets the general education requirement for social science – human behavior, Area D-1.

"A major motivation for me was certainly the desire to save students money. However I also want to make the material easy to access, for example, by sending students PDF documents, or by copying and pasting sections of the text into emails and so on. So it is not just that the books are free but they are also easy to access."

Mark StonereTextbook:
Public Speaking by The Public Speaking Project

Course Description:
Theory and technique of public speaking. Emphasis on organizing, supporting, and clearly stating ideas. Practice in informative and persuasive speaking. Meets the general education requirement for oral communication, Area A-1.

"I make use of textbooks as the basic source of content and use class time for activities that apply the content and practice skills. Therefore, I felt it was imperative that students had no excuse for not reading the course text."

"Further, I appreciated the fact that I didn't feel compelled to use every chapter to justify the high cost of a typical textbook. While I did end up using all the chapters, uses came organically from the course design, not a sense of compulsion. I value OERs for the freedom of choice, usability, adaptability, accessibility and convenience they provide. "
