We like to point our users to open access resources on the web that might be of use for your study or research. One such recommendation is Academic Earth (academicearth.org), an excellent site containing (mostly) free access to courses and lectures recorded by professors from institutions such as MIT, Stanford, Harvard, Yale and other colleges.You can watch an individual video or, if you're feeling ambitious, a full series of lectures on a single course. Topics vary from the philosophy of death to the American novel since 1945.
In total there are over 1,500 video hosted on the site, searchable by subject, university or instructor. Why not have a look to see what they have in your area of study or work? At least it's not hard to sneak out of the lecture halfway through...
