His YouTube videos are also incredibly good.

I have to concur. Markus Triska is best Prolog resource out there nowaday. Extremely well explained, using modern notations etc.

I'll second that. Incredibly good quality videos. The precision of the narration is simply amazing. Even if you don't intend to practice Prolog in your programming life, it's worth a listen.
