I’d rate it a pretty advanced topic. There is a lot more to say about tabling that would help people much more and that is nowhere documented. The most concrete are probably various sections of the XSB manual. David Warren once started on a book, but there is not more than a draft with, AFAIK no plan to finish it. I have a copy. I could ask David what he thinks about making it available online, maybe in some wiki format such that the community can use and enhance it?
