The Open Course Library is a project to design and share 81 high-enrollment gateway courses across Washington state community and technical colleges to improve completion rates and lower textbook costs for students. Phase 1 made 42 courses available in 2011 using various tools, while Phase 2 will deliver 39 more courses in 2013 using Google Docs for a more collaborative design process. Adopting the free open educational resources from these courses could save students up to $41 million per year in textbook costs if 25% of faculty adopt them. Lessons from Phase 1 informed improvements to project timelines and use of a single collaborative tool for Phase 2.
