It's a series of textbooks [1] based on lectures Feynman gave while teaching the introductory physics sequence at Caltech.

To my knowledge, no universities actually use the Feynman Lectures as a textbook for their introductory courses. However, some students who have already taken physics read the Feynman Lectures later and (self-)report a much clearer understanding.

FYI, the audio of the lectures is also available, but can be difficult to find. Afair, some of its a little scrappy at the start (poor recording setup?) but his delivery is great. I wish there was video available.

See also the Feynman Lectures on Computation.

UC Berkeley uses the books for their course. I'm not sure which specific class though.

I was a Physics PhD student at Berkeley and taught intro physics; none of the classes used Feynman as a primary text to my knowledge.

Perhaps they just started now, Physics h7B requires it. http://ninjacourses.com/explore/course/2433/#books

The Web page you linked to lists it as a "recommended" text, which means it is indeed not the primary text. The required text is Purcell.
