OpenCourseWare (OCW) refers to the free, open, and digital publication of high quality, college-level educationalmaterials, organized as courses, and made accessible to the public. "OpenCourseWare", launched in 2001 by MIT, is the most prominent example, providing the entire MIT curriculum as open educational resources (OER) for self-guided learning without registration or credit. These materials, licensed under Creative Commons, can include syllabi, lecture notes, assignments, videos, and free online textbooks, empowering anyone worldwide to learn and adapt them for non-commercial use.
