At Sinclair we are striving to reduce textbook costs by providing alternatives to traditional publishers. One model is OER (open educational resources) which are free, online textbooks you can view on any computer or device. Usually there is also an option to buy a low-cost print version.
If your course is using an OER, you should be able to find it linked in your syllabus.
The library also has links to most of our OER textbooks on our eBooks LibGuide:

If you can't find your textbook there, feel free to contact us.
