BCcampus Open Textbook Project
Initiative of British Columbia to make open textbooks avaiable for especially high-enrollment courses.

A non-profit organization committed to freeing the textbook from the limitations and costs of traditional textbooks. Our open and freely accessible LibreTexts provide a more engaging learning experience for students without the financial burden.

EdX, OpenCourseWare, Khan Academy and other online course sites offer course notes, reading and assignment ideas, and multimedia components that may have an open license.

Zero Textbook Cost Alternatives

Zero Textbook Cost Courses are courses that do not require students to purchase a traditional textbook. Readings for these courses may include recommended books, library materials, or materials provided at no cost by the instructor. Students may be asked to print out materials, if the materials are provided free of charge.

Zero Textbook Cost resources at the Emmanuel College Library include Library Course Reserves, E-books, Journal Articles, or Streaming Videos that are used as zero textbook cost alternatives or supplemental materials to enhance delivery of a course.
