The first entry in the FAQ doesn't directly address that issue but strongly suggests an answer, morally if not legally:
Q: Can I get a PDF of this book?
A: No, our contract with MIT Press forbids distribution of too easily copied electronic formats of the book.
I don't seen any obvious link to a licence that might confirm or contradict this impression, so if you need/want to know for sure you'll have to contact them to ask for clarification if you can't find it elsewhere.
It's likely not really about licensing. They have a contract with the publisher that presumably allows them to do certain things and doesn't allow them to do others. (I know that's been the case when I've signed a book contract.) Presumably, in this case, they're allowed to publish the full contents in web form on their site but not to publish them in a form that would allow someone to easily print the entire contents in book form.
