Tufts University
Browse classes from eight schools at Tufts University's OCW initiative. Choose from schools of dentistry, medicine, nutrition policy, veterinary medicine, arts and sciences, engineering and international relations. There are a handful of courses within each school.
Each course contains a variety of materials: PDFs of lecture slides, homework assignments and exams. While the navigation isn't the most streamlined, and not all courses contain complete materials, the courses are rich with searchable text and detailed lessons.
Additionally, Tufts offers a guide to Open Education Resources for even more useful links and libraries for teachers.
