These lectures are fantastic, please don't stop!

You mentioned David Marr's book. Given its age, I assume some parts have stood the test of time better than others - would you recommend reading it all or would you focus just on the first part you mentioned in the lecture? And are there other books you would recommend? (I haven't got very far though the lectures yet so apologies if you mention some later on.)

It is really the intro and first chapter of Marr's book that is still totally current. The rest of the book is brilliant but less representative of current thinking.
