The number of universities who are placing course materials online for the generally curious is growing, and the OpenCourseWare site provided by Tufts University is another fine example of this type of educational initiative. As with other OpenCourseWare sites, institutions can elect to include a wide range of materials, including lecture notes, syllabi, extensive bibliographies, and various media presentations. The materials here are divided in a number of ways, and most visitors will find it easy to navigate the entire site. First-time visitors will want to go ahead and click on the "Courses" heading, which will return a complete list of all the currently available course materials. Ranging from an introductory course on agricultural science and policy to a "physics for humanists" course, there are a number of real finds here. Finally, visitors can use the "Help" tab to learn more about the specifics of this initiative.
